Invalid session ( I already tried to restart/log out the game)

This has been going on since the day I purchased the MC (something like 2 weeks ago). The problem is I can not acces the realms at all (for the most of the time). Sometimes it works but mostly not. I have atteched MC output and the error that it shows. I am connect to the internet via Ethernet so connection should not be a problem.

I tried restarting the game or logging out of the account and login in. I also restarted my pc but it was for nothing.  I really do not want to depend on my luck if the realms are going to work this time or not. My friends can join realms just fine it seems the problem is on my side.
