Good evening/morning/night everyone.

I am facing one problem, whenever contest starts whenever i go to login by gmail then everytime codeforces give error like 504 (timeout) and it is written there that you are not eligible for this contest why is this is happening so frequently to me.Also when I login on android device it says that gmail login is not valid use password and codeforces handle.

I am using chrome and my internet is fast too.

Please give solutions/help for this problem.

And please dont downvote.

Thank you and have a nice day
