I have this very classic "Invalid session: please restart your game and the launcher" problem. But this time, restarting the game + the launcher didn't help. I checked the wifi. Then I restarted my computer, I uninstalled and reinstalled the game. Yet still the same "Invalid session" problem.
I don't understand what happened. May someone help me please?
Thx in advance.
PS: I've noticed that when I log in my launcher with the "remember me" button activated, it doesn't remember my password and it says: "Failed to login. Please login again."
After quite a bit of digging, I found that the problem is my minecraft id. When you start a game, it automatically shows the id you're playing on in the latest log file. Everytime you open minecraft, it loads a different one. But mine simply says all the time:
[19:12:25] [Realms Notification Availability checker #1/INFO]: Could not authorize you against Realms server: Invalid session id
So the problem is that my id doesn't load. Now the question is how to fix it.
