No Plex on Browser in LAN

Plex Media Server
1

Hi! From yesterday, I cannot connect to my Plex Server (Synology NAS) from my computer (Windows 10). At first it started on one of my Android boxes. I checked on PC and then saw it. I have downloaded the desktop app and there it works (For now) but from browser - not.

In browser saying - cannot connect securely with server.

If change Settings → Network → Secure Connection → to be Required, it says Sever is not available at the moment.

Have added in “LAN Networks” - 192.168.0.1/24 as my PC is part of network - no success.

Any suggestions pls?
