Plex keeps going offline, will only allow insecure connections

[msamproni_gmail_com]

Server Version#: 1.20.0.3181. (latest)
Player Version#: 8.4.2.19372 (firestick)
Web Version#: 4.40.1

Starting this morning I attempted to login to Plex (via firestick) and got the error NAS is Currently unavailable.
I logged into my NAS and confirmed Plex Server is running. I shut off and restarted. I was able to get in for a couple of minutes then the same thing happened. I can access via the web but the connection is not secure. I tried rebooting NAS. Same thing. I reboot router, same thing. I upgraded plex same thing.

Nothing was changed on the server since the last update a few weeks ago.

Any ideas? I am attaching log file. Thanks for any help (3.2 MB)

Thank you so much for looking at this. I just checked my NAS Storage. I am only using 62% of available space.

I have had this setup for almost 2 years the only thing that changes fairly regularly is the movies.

The music and photo folders rarely change.

Where should my music library be moved to?
