app.plex.tv is no longer able to connect securely as of Dec 5th 2025

Hi

On December 4th my PC had no problem connecting to Plex from Edge using https://app.plex.tv On Dec 5th it couldn't.

I've logged into the Synology NAS that has my Plex server, and by opening it on my desktop from the server using the ip address given have confirmed that under the network settings Secure Connections is set to Preferred.

I don't know what has suddenly changed, but I cannot access it as before.
