“No content”

On the Plex app on my Panasonic TV, as well as my iPad and iPhone, I am getting a “No content” error. When I go to menu>More to find All Libraries, I get an endless spinning icon. Last week, I had no problem in accessing my content. The NAS is fully accessible on Synology DSM, it’s just Plex that can’t find or play anything.

I have restarted both my router and the NAS. I would appreciate some assistance, thank you.

I have found out where to download the logs from the Amazon Fire Plex player, along with the device specification, if these would be of use?
