99% of stuff worked fine, but when I had issues it was a random error about server being under powered which wasn’t true at all lol. Someone on a forum suggested using the official windows app from the store and once I moved to that for client side access, never got the error again.
Keep in mind though, if you plan to do Plex from Hetzner, after Oct 2nd it won’t work anymore. But others here have suggested JellyFin instead. I’ll be testing that out this weekend, and if all is good moving over from Plex all together.
