Question / Help Formerly working stream to YouTube now is black with no sound.

The organization I work for (small government agency) streams some public meetings live. This original stream is broadcast in the building via a Windows machine. I take this public IP address and port, enter it into OBS as a VLC Video Source I am able to push it to YouTube. Works great. Or did!

Something has happened, and now that stream is black, with no sound. Basically an empty stream. However, I still see the live video if I paste that source URL into Windows Media Player. There were no network chnages, or changes to the stream that I am accessing, as far as I can tell.

Any idea what could be going on?

There are no errors, and nothing in the log looks weird to me, or even different from logs from a few weeks ago when this was working. But I've pasted one below for completeness sake. Thanks!

Does the source still play in VLC?
It does NOT play in VLC! This has allowed me to workaround by playing in WMP and broadcasting my screen. I'm still curious and annoyed at what happened to change this, but very thankful that your question helped me find a solution. Thanks!
