I understand and agree with you, as my YT live channels also work via PLM...
I'm just tracking this with you, as since the custom channels was added, I could never get YT live channels to work in FC, so I'm like you, still using PLM (which feeds VLC and my other iptv player).
@KineticMan Does the following provide any clues to you:

I'm not a dev, so I have no clues if it's important...
I had 3 YT Live channels working and did recordings from all 3.
That's why I didn't push it, I saw other folks had it working, so I figured it was something on my end...Plus I had my workaround in PLM

Unfortunately, I'm out of my depths here...Hopefully KineticMan sees something useful.

I just tested the share link and it detected fine for me. Possible you have some ad block on network? Just guessing.
All three of these result in the same error.

All three urls work with SLM.
FastChannels and SLM are both installed in containers on the same Synology NAS and both are using my ISP DNS. I have no ad blocker in use.
You can see the output from the FC and SLM containers yt-dlp in this post
Do any of these work for you?

All of my YouTube streams have stopped working. I'm pretty sure the FOBBV nest cam was working early this morning and am certain it was working yesterday.
The Channels Android TV client shows "403 forbidden" for all of them. Redetect fails as shown in your screenshots.
No clue what would be different between mine and y’all’s. Working 100% here. Same exact image you guys are on too. I’ll keep looking.
I'm also clueless.
Just for grins, I overrode the container DNS server to Cloudflare in case my ISP was doing DNS filtering.

Same error.
Sorry to hear that, but good to know it's not just me and Waffles.
Do you have SLM to try?
Out of the box, you do not even need to have PLM turned on to take advantage of these features. With just a base installation of Streaming Library Manager , you can input the following:
Some examples for the[URL_TO_CONTENT](and certainly not limited to) are:
- YouTube Live Stream (Specific):
https://www.youtube.com/watch?v=R7vrbiDi0Tc- YouTube Live Stream (Latest for Channel):
https://www.youtube.com/@KittenAcademy/live- Twitch Live Stream:
https://www.twitch.tv/timthetatmanvods- CBS News Live Stream:
https://www.cbsnews.com/live
thats whats so strange. i haven't touched that code in weeks- and SLM and FC use the same plugin (yt-dlp).
Have you updated yt-dlp recently?
SLM is using an older version.
could be that.
can u run this and send me the output pls?

Is this related to the YT issue that @babsonnexus had issues with earlier this year?
The issue I'm referring to was with PLM/SLM...
Pretty sure it's related to the JS Challenge solving @babsonnexus had to incorporate in SLM
