Based on the thread you created, our symptoms don't seem to be quite the same: you are experiencing a 90002, where everything in the 90xxx range seems to be a "connection to the server was abruptly terminated" event, with the last three digits specifying why, while I seem to be experiencing something more of a timeout that falls back to 10105, and I think 10xxx means the client side gave up while waiting for the server to respond.

The problem that you, and others, are experiencing may be related, but because I *am* able to log back in, just when the servers are exceptionally quiet, I don't think the root cause is likely to be identical.
