Suddenly no remote access

@Trap

  1. Your certificate was properly refreshed. Excellent

  2. Your server is visible to Plex.tv

EventSource: Got event [data] '<Message address=“XX.XXX.XXX.XXX” port=“32400” asyncIdentifier=“12e37b76-ad99-42fa-9f76-0c3c1e6efd37” connectivity=“1”

Everything I see here looks like your machine is not openSSL v3.0.0 compliant.
It seems as if it’s v1.1.1 (now expired as of Sept 2023).

(35, SSL connect error) (OpenSSL/3.1.1: error:0A000410:SSL routines::sslv3 alert handshake failure)

Do you have openSSL v3.0.0 installed ?

The Linux Tip refers to custom certs but also requires openSSL v3.0.0 compliance.

Lastly, Are you attempting to use the ‘plex.direct’ URL to access the host ?
