Running 3 Plex servers. Can't log into 0.9.9.14 but all others log in fine/OK. What gives?

Confirmed I can log into Plex with my account on 2 of the servers (WHS 2011, ReadyNAS) which run the most recent version of Plex. I had an old WHS v1 lying around and decided to revive it. Found out that only version 0.9.9.14 will work, which I installed successfully. When I remote into the machine, I see the dashboard. It will not let me log into my Plex/pass account. Why not?

I got my answer - Plex cut me off at the knees, looks like I’ll just have to go with the native windows services and nothing fancy like Plex on this server. Please close this question.
