I’ve had my QNAP TS-231P for years and have enjoyed using the Plex server software.
Unfortunately it stopped working and now displays an error message “digital signature expired”.
I’ve tried to work with QNAP, and they first asked me to download the .qpkg to re-install Plex… Didn’t fix the problem.
QNAP support then claimed that ports 32400 and 443 were not open on my firewall, which seems odd because I haven’t changed anything prior to Plex ceasing to function.
I’m really frustrated with this as it was working and now does not work. Plex just billed me for my subscription.
I’m almost to the point of tossing my QNAP and Plex in the garbage.
