Verification error and impossible to join any server

I've got the verification error (see screenshot).

I also have gray "Join" button for all servers.

I got that error as well, don't think it is anything to worry about.
How many servers are running 629?

Could be why you can't join.

There isn't an update for this build for you.

The servers will need to be running the same build you are.
