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

Could be as the developer he has something in his that we didn't get when we pulled the image 
Do you guys sign in with your YouTube account with Fastchannels and yt-dlp or is it anonymous?
It's a Custom Channel, no credentials like FrndlyTV
i.e. No bun, deno, node or quickjs available
And here's the same channel in CDVR using SLM that's working

in other news, Kaloopy is back too...
@KineticMan Update on my Custom YT Channels issue...
I can Detect the channel and also "Preview Stream" while on the Edit Custom Channel page...
Observation 1: I cannot play via the built-in player on the Channels or Guide pages...I get this new error:
Shaka error 1002 (NETWORK.HTTP_ERROR): Shaka Error 1002. manifest or segment request failed; check HTTP status, CORS, and network filtering Details: ["https://rr2---sn-i5f5ppuxa-ioas.googlevideo.com/videoplayback/id/CJVBX7KI5nU.8/itag/96/source/yt_live_broadcast/expire/1781426055/ei/JhMuavG3PO31sfIP5YfboAI/ip/72.253.16.202/requiressl/yes/ratebypass/yes/live/1/sgoap/gir%3Dyes%3Bitag%3D140/sgovp/gir%3Dyes%3Bitag%3D137/rqh/1/hls_chunk_host/rr2---sn-i5f5ppuxa-ioas.googlevideo.com/xpc/EgVo2aDSNQ%3D%3D/playlist_duration/30/manifest_duration/30/ss/1/bui/ARmQxEUESNFU7Zw5Xz-z5fxmk05TLqEIdv-pdcqcmXJcsVdH-0b40goE4FmPKVzB3-nzlJu7NYUWwsbS/spc/SQ-umg_9my6
Observation 2: I can play via the "Watch Fullscreen".
Observation 3: I cannot play via the Open in New Tab... the new tab opens but it just spins the Loading
So I'm curious how it works on the Stream Preview page:
Luck...
They share simliar codepaths, but slightly different. I've been meaning to combine them. I'll probably have to proxy the youtube stuff to get it to work consistently. will work on next week.

@KineticMan Feature Request: Search both Source Channel and EPG
On the Guide page, Is there the possibility to have the Search button searching both the Channels and the EPG?
Reason - Let's say I'm searching for Star Trek, currently it only searches the EPG... but it would miss all the dedicated Star Trek channels...
Currently, there are 7 dedicated Star Trek channels (available on the Channels tab), but on the Guide tab, it lists only 4 dedicated channels.
Another is let's say I'm interested in Las Vegas news... If I search in the Guide tab, I see a lot of Vegas but none of the news channels show up, and you can see them via the Channels tab...
I understand I can use the Channels tab, but I really like the Guide as I can see what is actually showing...
Hope this makes sense.
Thanks.
@KineticMan Feature Request: On the Guide page, remember previous searches...
Kinda like Youtube, the search box remembers previous searches, it may have a cap if necessary.
Along with this, is a means to clear all previous searches, and/or an option to delete one of the previous searches.
I've had Pluto For Channels running for some time now, and just today found Fast Channels. I don't have Fast Channels fully configured yet, but I'm guessing once I've done so I won't need Pluto For Channels anymore. Is that correct?
Also, I note that Fast Channels seems to be asking for some Pluto credentials but I don't think I ever put in any credentials into Pluto For Channels. I checked my P4C server today and there are spaces to input credentials but they are blank. Can someone clarify the P4C credentials situation to me?
