Plex is incredibly unstable

Plex Media Server
1

Server Version#: 1.43.3.10861
Player Version#: 1.112.0.359-0d79a49f

My main plex server (ip-86.248/24) is running on Docker < Ubuntu < Proxmox. I can visit & play on it anytime, if I login via local ip of the server on browser.

But on Plex app on Windows, Android, iOS, macOS, even on browser via plex.tv - that server comes & goes, randomly. Even when i’m playing something that server would suddenly disappear from the app.

Obviously there’s nothing wrong on the server, its always available on the ip. All of my devices, including docker itself is using gateway ip as DNS.

Things I’ve tried:

  • Relogin to all apps
  • Delete cache of apps
  • Toggle between every settings on network page
  • Server is claimed

Just an initial observation, don’t put spaces between the network addresses in “List of IP addresses..”

Also for LAN Networks.

192.168.86.0/24, 192.168.87.0/24 ← incorrect
192.168.86.0/24,192.168.87.0/24 ← correct

Fixed it, didnt fix the server disappearing issue.

Is there a reason for the custom user access URLs? If not, then remove them and restart Plex Media Server.


To see the server addresses registered with plex.tv, use https://plex.tv/api/resources?includeIPv6=1&includeHttps=1&X-Plex-Token=<your_plex_token>.

For example, if your token was 1a2b3c4d5e: https://plex.tv/api/resources?includeIPv6=1&includeHttps=1&X-Plex-Token=1a2b3c4d5e.

Obtain a Plex token: Finding an authentication token / X-Plex-Token.

Also, try a public DNS server such as 1.1.1.1 (Cloudflare), 8.8.8.8 (Google), or 9.9.9.9 (Quad9). Some ISP DNS have problems resolving Plex hostnames.

My router is using google & cloudflare dns. And all other devices are using router’s DNS. So there shouldn’t be a problem with DNS here.

So that the clients can find the server, as i’ve toggled between every settings here.

I checked this. Here also my linux server (Mini PC) isn’t constant. It comes & goes.
