The current pre-release of the client ("pioneer" in the version) is only compatible to itself. So you can only play with other testers. Please be aware!
Apparently, Firefox hates me. I had to switch my defaults over to Brave to get the login window over there and get in. After clearing the cache in Firefox it kept trying to connect to a 'server' on my local machine after the weblogin.
Oh, well. At least I can play again now!
