PMS 1.43.4.10903 (linuxserver/plex, Docker host network, Unraid).
Machine identifier: ff2329374c2562c5e01401ba6de7b816e046e510
Cert CN: *.43dd6f289c4e4b31aed49337f5dee64c.plex.direct, issued Sep 12 2026, chain is YR1 → ISRG Root YR with no X1 cross-sign.
Port 32400 is confirmed open from the internet (canyouseeme and a cellular phone both reach /identity over http and https).
The reachability prober fails every time:
CERT: incomplete TLS handshake from [::ffff:34.239.73.157]: tlsv1 alert unknown ca
MyPlex: mapping state set to ‘Mapped - Not Published (Not Reachable)’
Removing CertificateUUID and restarting re-fetched the same certificate.
Could staff please revoke/re-issue this server’s plex.direct certificate so it comes back on the cross-signed chain?
