In this article, we will try to figure out why this error appears and what needs to be done to solve it.
If you get the error "Invalid session. Try restarting the game" or "Login error: invalid session", then the first step is to try to perform the actions indicated in the error text itself, that is, restart the game. It is possible that during the connection there was some kind of failure that prevents the game from starting, and after restarting it, the problem will disappear by itself. At first glance, this solution may not seem effective, but in some cases it can help in solving the problem.
Hamachi
If restarting the game did not help and the error still appears on the screen, this does not always mean that the problem is with the game. There may be a problem with the online game application.Try restarting Hamachi, after which, most likely, you will be able to create a session and connect to it.
If this did not help and still an error appears with the text “Invalid session. Try restarting the game", you can try restarting the game without closing Hamachi. Sometimes such a solution can help in connecting to a network game.
It is also worth trying to completely remove Hamachi and reinstall it. Then go through the authorization process and resume the connection attempt in Minecraft. The same action should be taken by your friend whose session you are trying to join. These actions very often solve the problem with the error.
Deleting a game
The next possible solution to the problem is to uninstall the game and then reinstall it. Given that Minecraft is an extremely unstable game, this method has the right to life. After reinstalling the game, log in and try to create a game session again or join an existing one.Also, it is worth noting that such problems can occur on computers with outdated hardware. What causes this, no one knows, because Minecraft itself does not have serious system requirements, but reinstalling the game very often helps to get rid of errors.
Viruses
The cause of various kinds of errors may be infection of the computer with some kind of virus or viruses. It is no secret that viruses can not only disrupt the performance of applications, but also cause serious damage to data.
To rid your computer of malware, run an antivirus and perform a thorough scan of all hard drive partitions. If you find any doubtful elements - try to cure them with an antivirus. Before all these actions, it is worth uninstalling the Minecraft client in advance, and installing a new one after curing the detected files. After installing the new client, try connecting to the game session again. If the cause is in viruses, this option will undoubtedly help you get rid of the error “Invalid session. Try restarting the game."
Game version
Also a very important point is the version of the game itself, that is, when using different versions, players cannot connect to each other. Also, it is worth noting that the latest versions may have a sufficient number of bugs, due to which there may be a problem in connecting to the session. Thus, if you and your friend with whom you want to play have different versions of Minecraft, then the error “Invalid session. Try restarting the game." Ideally, you should use the same versions to solve this problem.Pirated version
In addition to all of the above, the reason for the error “Invalid session. Try restarting the game" may be a pirated version of the client. The fact is that in version 1.7.5 the authorization system has changed, which is why it is impossible to play on a local network without a license. Want to play with a friend, but on a pirate? There is a way out!In the folder with the game, use the search to find the file “server.properties”, the line “online-mode=true” will be located there. In it, you need to change the word true to false. These manipulations disable the license agreement check, which is not available in pirated versions. Thus, you can get rid of the error "Invalid session. Try restarting the game" and play with a friend on a pirate.
Today, the game servers of the legendary Minecraft sandbox perform hundreds of millions of game sessions every day. Unfortunately, the number of authorization and launch errors for players is also considerable. One of these problems was the Minecraft login error “Invalid session. Try restarting the game." It becomes obvious that restarting does nothing. Today we will tell you why this failure occurs, as well as what to do to fix the invalid session error.
Why does the error occur
This problem, by and large, is caused by the fact that since Minecraft version 1.7.10 it is impossible to play on servers without a license. Thus, the developers are fighting pirates and, of course, trying to get hold of finances by increasing sales. The Bad Login error also applies to problems with the lack of a license key. But in addition to problems with the lack of a license, an error can appear in rare cases in official versions.
Login error "Invalid session. Try restarting the game"
The rest of the Minecraft login errors include a mismatch between the game versions and those required on the server, the need for a specific launcher (Tlauncher, MineCraft Only Launcher) or the absence of certain mods. But we will specifically analyze the stated error "Failed to login: invalid session (Try restarting your game)". There are not very many solutions here, but nevertheless, those that are, work in most cases.
What to do with the "Invalid session" error
So, the easiest way out is to buy a licensed version of the game - the way out is simple, but, of course, it will require money. Another way out of the situation is to create your own local MineCraft server, where you can play with a friend over the network. Here is a fairly clear video instruction on this method.
We use the Ely.by service
You can also bypass the license using an alternative authorization service - Ely.by. Authorization and launch through this service is quite simple. Here is an overview video:
Conclusion
Despite the fact that the Minecraft login error “Invalid session. Try restarting the game" is quite common and is aimed at fighting crackers and pirates - the developers only caused a new wave of discontent and the development of folk methods of circumvention.
What is a login error in Minecraft: invalid session, restart the launcher and the game? The popular computer game Minecraft, unfortunately, has many problems with launch and stability.
Many users encounter unexpected errors despite the fact that the game has been working fine up to this point. One of the most common problems is the inability to connect to the game server with the following message: "Invalid session". In this article, we will consider the main ways to restore the performance of the game client.
Why does the login fail?
The main reasons leading to this error in versions 1.12.2 and 1.13.2:
- lack or temporary loss of connection to the network;
- using an unlicensed version of the game;
- malicious software on the computer;
- blocked by a firewall or antivirus;
- attempt to connect to the official server using a pirated version;
- discrepancy between the version of the game and the installed modifications to the requirements of the server.
Often, the cause of the loss of connection is the update of the game or the installation of new mods. In this case, reverting to the previous version and disabling mods will return the game to a usable state. If no changes have been made to the game client since the last successful launch, then the cause should be sought elsewhere.
How to fix an error?
The easiest way is to restart the game. After closing the client, open the "Task Manager" (alt+ctrl+del for Windows users) and close all processes related to Minecraft. Better yet, restart your computer completely.
Since the error may be in the Internet connection, you should restart the router. To do this, you just need to disconnect it from the power supply for 5 - 10 minutes. Rebooting the router is especially useful for those who use a connection with a dynamic IP address.
If the above methods did not help, then you should clean the registry using the CCleaner program and close all other applications while starting Minecraft. Especially those that require an active internet connection.
Reinstalling the game might also fix the issue. You should carefully check the compliance of the version of the game with all participants in the connection. If unofficial mods are used, then it is better to disable them.
When using the licensed version, problems with the performance of the game occur much less frequently. But even the owners of pirated versions have the opportunity to play online with their friends or on unofficial servers. Most often, the Hamachi program is used for this, which allows you to bypass blocking by developers.
To do this, you need to download and install the Hamachi program. Disable everything that can block the connection (firewall, antivirus and similar defenders). After that, you need to create a network to which all participants in the game must join.
After that, in Minecraft, you need to create a new world, in the settings of which the "Open for web" option must be enabled. Next, you will need to enter the IP address and port. It is important that all players connecting to the server have the same version of the game client. Otherwise, the game will not work.
In the game folder, you can disable the protection built in by the developers. To do this, you need to find the server.properties file and open it with any text editor.
Having found the line online-mode=true, you should replace the value "true" with "false", without quotes. After that, you need to save the changes and restart the operating system.
When using Hamachi, the server and port address is assigned by the game, which means it will need to be passed to anyone who wants to join the game session. For players using the same local network, you can find out the address in the game client itself using the ipconfig command.
There are many ways to find out your IP address on the Internet. One of the fastest and most convenient will be using the site 2ip.ru, where you can instantly find out the address of your computer.
So, if you play Minecraft, the “Invalid session, restart the launcher and game” login error is solved by a number of the steps suggested above. If so, please share your experience in the comments.

- I can't play on the server!
1) If you get an error "something related to java", then try disabling your antivirus and / or firewall and check your Internet connection.
2) If the error is "Bad Login" or "Invalid session" ("Invalid session"), then the error is due to the fact that the server uses a premium authorization model, that is, pirates (or just people with other launchers) to this server won't let. Try to enter this server using the launcher offered on the website/page of this server, or use the official one.
I can’t play on the local network: it says “Invalid session”
Only premium users can "open" the server for the network. Create a separate server (We have an article) and write online-mode=false in its settings

Result: 
With the regular release of updates, Minecraft developers make important and not so important updates, which often cause errors in users. Some problems are fairly easy to solve, while others require a lot of head-scratching. If you see a window with the message: “Login error: Invalid session (Restart the launcher and game)”, what should I do and how to solve the problem? We will talk about this in the article.
Reasons for login failure
Most often, a window with this message is seen by players using software without a license. Thus, the owners of Minecraft complicate the life of the owners of pirates, making the game impossible. It is worth noting that the protection mechanism often leads to an error for the owners of official content. In particular, problems with login can be traced in versions 1.12.2, 1.17.10 and higher. Of course, playing on official servers with a pirated game has become almost impossible.
Possible reasons include:
- problems with mods and their incompatibility;
- errors in the game - banal bugs;
- connection problems - broken network settings.
What to do with the “Invalid session” error?
It’s worth starting with what is advised in the window: restart the launcher and the game - it’s possible that the failure is really single. If this did not help, and there was no problem before, then it is worth restarting the PC - it may be some kind of operating system or network failure. A standard set of actions will not be superfluous, namely:
Of course, this helps in isolated cases, but it certainly will not be superfluous.
The easiest ways
More complex options
If the previous solutions were simple and effective, then the following methods in fixing “Invalid Session” are more complicated:
- You have the option to disable verification on the downloaded server. To do this, in its folder, find a file called “server.properties”, and opening it with Notepad, change the line “online-mode”, the value from “true” to “false”.
- If a message appears when trying to play on a local network, it indicates an incorrect configuration. In particular, the port or IP address may be incorrect.
- For remote gaming over a local network, the Hamachi application is often used. It is worth boiling the settings again, try restarting / recreating the LAN. One way or another, it is advisable to use this particular software for a remote game on a local network. An important point: it is recommended to set the IP of the machine manually in the settings of the home router. This solution can be very helpful when setting up.
- Another interesting solution is to use the Ely.by service. This resource is an alternative authorization service that allows, roughly speaking, to make a licensed version of your pirate. More than enough for a local game. See the video below for how to do this.
Summing up
As you can see, in Minecraft, the login error “Invalid session, restart launcher and game” is solved in many ways, and these are just the most effective solutions. Of course, with each release of updates, the number of workarounds will be reduced, but new solutions will definitely appear.
