Invalid session Try restaring Minecraft

Hi

When trying to connect to relams I get the following error message: 

Invalid session

Try restarting Minecraft.

 I have restarted the launcher, the game, the computer and also reinstalled Minecraft. Same thing happens on my three computers on my three different accounts.

Can you look into this please? I have searched the forum and found two more examples of this on the same date, butboth of those tickets were closed due to them not being written in English.

 

BR,
