I'm sorry. I don't have a clue what you just said here. I understand the pre-release version. Everything after that is a bit to vague for me to understand
Do you use a m3u url as your source? If there is a port in the url it may not process it properly
For instance, if you use m3u and anywhere in your process the m3u has a port 80 like this:
https://myprovider.com:80/mytv.php?type=m3u_plus&output=ts
Remove the port number from the url.
https://myprovider.com/mytv.php?type=m3u_plus&output=ts
That change and using the prerelease should solve the issue.
Ah, I understand now. No, that was not the problem. I was able to upgrade the container using the Server Information pull down. After that, it began to work.
Thank you for your massive assistance!
Channels should support custom tags in m3u files used to fetch streams like User-Agent or Referer. I have to fiddle with nginx config used as a forward proxy to overcome this.
Did this get reverted recently @eric? I'm getting 461 again and after some debugging in my docker container shell, I tested a bunch of different user agents, including dummy ones, null ones, and VLC ones, all of them worked fine. However, when I specifically tried the user agent: Go-http-client/1.1 is when I received 461. I suppose it's possible whatever non default user agent channels uses got blacklisted but it feels less likely the case 
Edit: adding custom user agent to m3u works, meaning channels added support for custom user agents. see my post here Stream fails in Channels app and Chrome but works in VLC - #35 by addd45
No, nothing has been reverted.
