Same issue for me since the update yesterday.

I get the timeout and the attach failed to drop other attach error messages. been down for almost 24 hours now.

Same issue for me

same, cannot login now.. yesterday i was playing without problems..

Same as others, Cannot log in since the last update

After the update, I tried to update today and got this error:
Unable to login
Authentication failed for (username)
Timeout

Unable to Login
Authentication failed for "username":
Attach failed to drop other attach

Same as op, Authentication failed: Timeout or Attach Failed to drop other attach...

Same as op and all others listed below.

I'm getting the same bug with the Authentication failed: Timeout

I also cannot log in... for some reason. Attached is the log. Seems server-side. I have restarted me computer. Currently stuck on a Waiting For Server screen. The Check Status button says all systems are up...

I am unable to log in. Just getting a message: Unable to Login - Authentication failed for [My Username]: Attach failed to drop other attach,

Can't log in just want to play

unable to login. Authentication failed for [username] attach failed to drop attach

Seems to work now(?)
