Thanks @BigWheel No, I’ve got no cert-acquisition errors on my end. I grepped every log and there are zero Error acquiring new certificate / Failed to upload CSR / 429 lines.
The server is serving a valid cert right now: a Let’s Encrypt *.plex.direct cert, valid May 12 → Aug 10 2026. The only CERT: lines I have are benign local TLS handshake aborts from a device on my LAN (sslv3 alert bad certificate) nothing to do with acquisition.
What I’m actually experiencing: since Jul 5 my server randomly disappears from my account’s server list. At any given moment it’s missing roughly 60% of the time, it flaps in and out every few minutes. The effect is that anyone whose app does a fresh lookup during a “down” window sees no server / empty library, while anyone already connected keeps streaming, so it looks random, “some people can, some can’t.” I can’t see my own library from a fresh client either, even though the server is up the whole time and serves perfectly over a direct connection.
That lines up exactly with the one failing signature I do have, the mapping publish looping on 422, which never lets plex.tv mark the server reachable:
MyPlex: mapping state set to 'Unknown'.
MyPlex: Published Mapping State response was 422
MyPlex: mapping state set to 'Mapped - Publishing'.
[EventSourceClient/pubsub/...] MyPlex: mapping state set to 'Mapped - Not Published (Not Reachable)'.
MyPlex: sendMapping resetting state - previous mapping state: 'Mapped - Not Published (Not Reachable)'.
So the cert path looks healthy, it’s specifically the mapping/registration publish returning 422, continuously since Jul 5. Is there any chance you could reset the mapping/registration record for machineId 37973b185ea6bddbd4772435a73b5144c5fd91aa?
Happy to pull any other logs that would help. Thanks for the quick look!
