Server Version#:1.28.2.6151-7000
Player Version#:N/A

I have installed mentioned version od Plex server on SYnology DSM 7
But when I try to open app from DSM every time it ends on page
https://nas.svecpetr.com:32400/web
with HSTS error:

Webové stránky prokazují svou totožnost pomocí certifikátů. Firefox nemůže server nas.svecpetr.com:32400 ověřit, protože použitý certifikát pro něj není platný. Certifikát je platný pouze pro *.ee40e13e051b4c77aa37fdad41b65792.plex.direct.

Kód chyby: SSL_ERROR_BAD_CERT_DOMAIN

I suppose this is a domain you configured for your NAS?
If you want Plex to use that domain and its encryption, you’ll need to configure your server accordingly (see Settings > [Server Name] > Network > Custom certificate ... options).

Using the hosted web app or accessing your Plex Media Server through the Syno’s local IP address also shouldn’t give you that problem.
