Remote access unavailable after December update

Plex Media Server Remote Access
1

Server Version#: 1.21.1.3830

Hello, after December update PMS can’t make available remote access, and in my network it connects only without a safe connection with a loss of the video quality.

My router has always been setted as today, I didn’t make any changes, and before the update remote access worked.

Anyone knows how to solve this problems?

I removed all my signed in devices and re-signed into each and this fixed remote streaming connectivity problems for me.

Every solutions was useless.
The problem solved itself with the last update of PMS
