Having this problem for the last 10 days or so. Facebook Live, using the FB connection inside streaming, throws a stream error that ends, generically, in "I/O error"

Have tried persistent key, random keys, going through the facebook settings dialog in streaming, using a custom rtmp url, yeah.

Have sent error logs to vMix through the software

I am seeing a "stream duration limit reached" error at a different location (using OBS not vMix) as soon as I press start streaming. I only bring that up because it's the same kind of weird "stop as soon as you start" error.

This seems to be a Facebook related issue. Wondering if Facebook has a STORAGE limit for Facebook Live videos and that's the reason it won't start the stream. I mean we have 60+ hours of video that has been done with FB Live...

Any thoughts/advice greatly appreciated!
