It looks like Rayna only operates against the URL of the Plex server available on the local intranet. I've even tried signing out and signing back in - in which case, I'm able to successfully sign in and am presented with my server to select, but I am unable to proceed beyond that point. Looking at the developer tools, I can see a request to /init that never resolves - I speculate that the tool is trying to reach out to my Plex server using its intranet IP address and blocking indefinitely on a response that never comes (since there's nothing listening at that particular port and address on the cafe's network).
