Minecraft is a hugely popular multiplayer game, and getting an error that prohibits you from connecting to servers online may be quite annoying and ruin your gaming experience. When you sign in with your gaming credentials and try to log onto any server, personal or otherwise, the problem appears. The error indicates that the issue is with the session and has to do with the player’s login information or attempt. We’ll try to figure out how to fix the “invalid session: please try restarting the game” error and get you back to effortlessly connecting to your server and crafting and surviving in Minecraft’s harsh and deadly environment.
Before you try anything, restart your computer and make sure all unneeded apps are closed before running the launcher and attempting to log in. This easy solution might sometimes help you get around errors.
Minecraft Invalid Session (Fix)
1) Restart the game
It is recommended that you restart the game and its launcher, as well as re-login to your account. This will assist to refresh the session files and generate a new session with no problems logging in. Also, just to be safe, make sure you run the game as Administrator.
2) Session timeout or multiple logins
Your session may have expired before you had a chance to connect to your server as a result of the problem, or it may have timed out due to inactivity. Try logging in with your account again, and make sure your account isn’t logged in anywhere else, as this could interfere with your session. Before attempting to log back into your account, close all Minecraft windows and log out of all places.
3) Reset account password
There’s a potential that someone gained access to your account and exposed it to fraud and misuse. In this situation, immediately change your account’s password and ensure that only you have access to it. After that, try logging back in to see if anything has changed.
4) Reinstall mods
If you started getting this error after downloading a new mod or installing one you already had, it’s likely that it’s the source of the problem. Before attempting to get back in, try removing that particular mod and then repairing the game in Windows settings for good measure.
5) Reinstall Minecraft
If all else fails, it’s time to wipe your computer clean of Minecraft and all of its files and start over. Uninstall the game and ensure sure all Appdata files are gone before downloading the installer from the official site and starting the download again. When your game has finished downloading, make sure your windows firewall is turned off, and then try again to check if your ‘invalid session’ issue has been repaired.
