Ok, got back in and managed to get Blitz unencrypted to deploy properly, with some trial and error. Here's a list of what happened:
Updated from 8.6test3 (where I had already set up Blitz Unencrypted, just hadn't deployed) to 8.6test5
Tried to deploy Blitz on 8.6test5 and got the above not ready error
rebooted server from SSH session
Server came online normally but without port 22 access, so couldn't SSH
Used Hetzner to perform a reset on the server, twice.
Regained SSH access but was immediately prompted that Traefik wasn't deployed correctly. (Had been working fine till this reboot)
Ran pgupdate again and selected 8.6test5 again.
Was able to deploy Blitz this time.
Traefik is now failing to deploy so I've had to open port guard to access apps.
Not sure if any of these things are related to each other or if my luck just sucks but thought best to detail it all just in case. I'm testing now to see if Blitz is actually working correctly, will update soon
No. Pg is modular so when you run the pgblitz mod, it's independent of others. The lack of port 22 access is something else as PG does nothing with the port or ssh . The red flag was when You said your stuff didnt change.
