Unraid Community App Store

You can try strace on the process and see what syscall is returning EPERM

Who makes those dockers? I moved to a linuxserver made ubuntu focal image so I didn't have to keep updating my own ubuntu image. I don't have any networking issues with mine in host mode, in bridge mode, or behind a VPN and I messed with all of that last night. I'll try using a different base image this weekend.

Also, which Unraid version are you running?

My dockers are from a variety of sources, but mainly Linuxserver.io, including the Plex one. I have been running the 6.10 release candidates and just updated to 6.10.

would this be in unraid or the container?

Ok I’ll look this weekend. I’m using the same base image they are so maybe I’ll see something

I updated the container, can you give it a try?

Sorry for the delay, unfortunately it was the same result.

I did run a packet capture and right before the issue happens I see a missing ACK to the HDHomerun, and then a bunch of duplicate ACK messages and things seem to go off the rails there. In the below screenshot .141 is the my hdhomerun and .164 is the channelsdvr

Can you get a shell on the container and then in /tmp download the speedtest binary (https://install.speedtest.net/app/cli/ookla-speedtest-1.1.1-linux-x86_64.tgz), untar it, and then run it? It should show if there's any packet loss at least going out of the container. Hopefully it's:
Packet Loss: 0.0%

oddly enough it didn't test for packet loss

This is just odd... try ip -s link show {interface}?

So high level question, what's the advantage of using the Community App vs the Docker template? Is it based on the Docker template with more things preconfigured for hardware transcoding?

Ease of use. The Community App pulls from a github repo that hosts…. two templates, one for Intel and one for NVIDIA. It’s based on my docker container (not the official Channels) and they have always been preconfigured for hardware transcoding and specifying the user in the container (so permissions for the mounted file will be nobody:user and not root:root). The base OS for the container is a linuxserver baseimage for Ubuntu 20.04. The container can be found here: https://github.com/timstephens24/channelsdvr-docker
