i keep getting Errors, what to do?

yea so i keep getting errors like "Connection closed" and stuff for the past 2-3 days, can barely do anything on the game anymore. Tried using different browsers but didn't help. Asked my friend to login on my PC and his account works without any problems.
Anything i can do to fix this?
Thanks

What kind of errors do you get Flashing? Can you take some screenshots of the errors?

Also, as I understand you are playing on the Web platform - Did you try clearing the browser cache and cookies? Try and see if it helps.
