New Host Transcoding Issues

[alleycat]

I recently changed my jellyfin host to a new machine. It has an Intel i7-13700. Transcoding seems to work fine, except when trying to load 4k movies in browser. The transcode log: https://pastebin.com/mhWUnBKx (Password for non-indexing purposes ULVAAL8Jid). The movie loads, but never plays.

I'm using a web browser (firefox) as the client for testing purpose. Other clients are remuxing, and seem to work ok. Transcoding 1080p works fine. Not sure what the issue is here. Could use some help, please let me know whatever additional information is needed to troubleshoot.

Try using Microsoft Edge and see if that works. Firefox may have issues with 4K.
