This error shows that you are still transcoding. Make sure your settings look like this on the client
I was just continuing the discussion from the other thread, specifically what @tmm1 asked the other poster.
Recreate and post some logs of this happening. Also what source are you trying to play?
Also do a speed test from the client to the dvr in settings and post the results of that as well
Nothing in this occurred when the playback paused and I saw the buffering spinner.
Generally the transcoder error I shared doesn’t appear. Generally just very stuttering playback.

Speed test:
As for what I’m playing, it is broadcast TV (in this case BBC 1 HD). This comes from a silicon dust tuner.
I note from here: What is hardware video transcoding?
That there is no mention of mac hardware being supported for transcoding - not that I am using transcoding now, however it would be good to know if there’s any mac hardware that does do transcoding well.
Are you using integrated tailscale on the Channels server? Im trying to figure out why you have a cgnat address for your HDHR.
Post your network design with ip addresses for each component and maybe we can try and sort this for you.
Please do a traceroute from your remote location to your home server and past the result in to this thread
Not sure what you need here but I’ll summarise how things are set up:
- Mac mini channels server (local IP and tailscale: 100.123.190.109) - due to current situation, it is using WiFi but was and will be using Ethernet again soon.
- synology NAS store (local IP and tailscale).
- device (iPhone) streaming to 100.123.190.105 (also tried iPad, same result).
- various UniFi kit, including UDM Pro
Do this as soon as you possibly can. In fact for testing I would run a temp ethernet cable to test.
Are you using the integrated tailscale from Channels? If so I would recommend setting up your own tailscale server. The channels implementation of tailscale is not great. Set up your own tailscale server and run it as an exit node.
I have Tailscale running on channels server built in and on the Mac mini.
Traceroute to channels server takes about 4 seconds (!!!):
traceroute to 100.123.190.109 (100.123.190.109) , 5 relative hops max, 52 byte packets
1 unifi.localdomain (192.168.1.1) 3687.125 ms 3703.439 ms 3706.631 ms
It seems to fail to complete. Another run:
traceroute to 100.123.190.109 (100.123.190.109) , 5 relative hops max, 52 byte packets
1 * * *
2 unifi.localdomain (192.168.1.1) 1747.181 ms 1763.380 ms 1767.754 ms

unifi.localdomain (192.168.1.1) 609.636 ms
I’m not there right now so can’t experiment with running a cable immediately but I’ll do that. Will also look at using the tailscale on the Mac mini and turn off the channels one.
Btw, thanks for your help
1st problem. Turn off tailscale on the channels server settings. It will literally casue you nothing but problems.
My setup is a bit different than yours. I run my tailscale server on a linux VM in proxmox and set it up as an exit node. I would set your mac mini as an exit node. Exit node setup guide Then on the iphone, conect to tailscale and select your mac mini as the exit node. On the channels client set the connection to at home and enter the local address of yiur mac mini (192.168.1.x). Dont enter your tailscale IP here, you want the actual physical local address. It should connect and hopefully work without issue.
I think I might struggle with replicating your set up. I don’t want my iPhone to use my Mac mini as an exit node
Using the Mac mini tail scale address seems like worth trying.

I would at the very least turn off channels integrated tailscale and then just set your channels client to "at home" and then enter the tailscale addr of the mac mini.
The part that was puzzling to me was that the client looked like it thought it was away from home as it was remuxing to hls. It should behave as if it were directly connected to your network.

This was when connecting to the Mac mini tailscale address (at home) but before disabling the channels tailscale

Im out of ideas except i would ditch tailscale to rule it out completely. Open the port on your router and enable remote streaming in channels. The connect away from home on the channels client and see if everything works. I think you have some wierd routing issues on your network as the server should not be transcoding if you are connected "locally" throigh tailscale.
Bypassing tailscale should prove if that is the issue.
Ok disable the channels tailscale. You literally never want to enable that for any reason. Its terrible.
