Zoom streaming to custom service won't load beyond "preparing stream"

[Jtmedina]

For the first time I was unable to custom stream a zoom meeting, as I've done for months/years without issue before. Anyone else having this issue? Using restream to stream to Facebook and Youtube simultaneously, but when the page starts loading to "preparing to stream" it freezes about a quarter way through. Tried half a dozen times, and on multiple computers.
