Unable to play video remotely - s1003 (Network); the player cannot recover

I was able to find the solution to my problem in this post.

Plex Server Playback Error Code s1003 (Network)

I suddenly can’t stream anything from my Plex server to any of the devices or even play them on the Windows PC that runs the server.I have several device including a Plex TV, Roku, android app etc., and none of them will stream anything from my libraires. It seems like the streaming content included with Plex will work on the devices. I uninstalled the Plex software and reinstalled it, but nothing changed. I did set the “Allow Failback to Insecure Connections” to “Always”, but it did not help…

I removed the check mark next to "Use hardware-accelerated video encoding " and I was able to play my videos remotely from the Plex android app and the Web,
