Ah, so I've been switching servers (going from a dedi to self hosting + cloudflare to see how it goes, and if it sucks, probably switching to a smaller dedi). So far... so many wierd small glitches. The nginx will refuse to start if any of the downstream containers are down (and I accidentally put the hostname I used in testing rather than the correct one for one), my firewall had the wrong default zone, so opening ports failed
(and that's a subtle one, and I don't know why the default zone changed..) ... its finally up tho, so I can start moving containers over and hoping nothing else fails
