SOLVED: Playback error "This client isn't compatible..."

[Representing_all_cats]

Thanks for replying @Venson. Unfortunately I’m confused by your response…

Those logs are for two files that refuses to play at all, so ‘barely’ working would be a gross overstatement.

The server will transcode the exact same files from HEVC 4K or 1080p to 264 720p and play on my iPhone in the Safari web player just fine. It will do it at 50-60 fps for a native 4K, and over 300 fps for a native 1080p.

I also tried playing in Chrome on a different computer through a VPN this morning (accessed JF server via https). No trouble transcoding HEVC 4k to 264 and says 60 fps in the playback info.

Can you help me understand why transcoding to my iPhone and a 'remote' Chrome client on Windows works flawlessly, but to a local Chrome client fails completely? It doesn’t seem like the server hardware would be at fault in this case.

Note: I understand that VLC won’t require transcoding, I only mentioned it as a troubleshooting step.

Thanks again!
