Issue: Setup SSL certificate for Plex Server from Synolog DS920+ NAS

[brace110]

Server Version#: Version 1.25.6.5577
Player Version#: Kodi app on TV, iPhone, Ipad

I just upgraded to DSM 7 and installed the latest Plex Server (manual installation via package center)
I used to be able to create a certificate using the current certificate I have running for the NAS.
You export the certificate, thereby receiving a private key, cert and chain file.

With this command: Setup Let's Encrypt certificate for use with Plex Media Server on Ubuntu · GitHub

sudo openssl pkcs12 -export -out ~/certificate.pfx \
    -inkey /etc/letsencrypt/live/myhostname.no-ip.org/privkey.pem \
    -in /etc/letsencrypt/live/myhostname.no-ip.org/cert.pem \
    -certfile /etc/letsencrypt/live/myhostname.no-ip.org/chain.pem

You can create a .pfx file, then all you had to do was upload it to the NAS server and enter the details in Plex, see images

But the Plex server doesn’t seem to be validating the SSL anymore.
For some reason the common name is complete unrelated to my server url:

How can I add a PFX file correctly so my Plex is under https again?

1. Make certain your certificate includes the CA in the PFX
2. Place the file where user PlexMediaServer can get access to it.

• Placing it at the top of PlexMediaServer shared folder is a good place for it.

3. Settings - Server - Network - Show Advanced.
4. The first group of entries are where you enter the certificate info.
