at this point, you are redirected to https://testbot.winehq.org (the old server)
testbot.winehq.org is not the old server. It's the same server as newtestbot.winehq.org.
There's an issue with cookies, though. You may have cookies from the old testbot.winehq.org, but those don't work for the new testbot.winehq.org. Likewise, you may cookies from newtestbot.winehq.org, but those aren't used for testbot.winehq.org because the domains don't match. So, you may have to log in to testbot.winehq.org again (using the same account as you use with newtestbot.winehq.org).
