stream it does not work. It has to be obs related cause restreamio on the website worked.
Correct - your OBS settings don't match what restream.io is requiring for input.
I'm not a restream.io user, so can't say for sure, but I'd expect just as you have unique stream key or other such settings for YouTube, Twitch, Facebook, etc, restream.io has its own settings it requires for stream input. You'd be mistaken to assume stream settings used for another provider (incl B-frames, Audio sampling rate, etc) will work at restream.io. some might, others may not.. you have to check and know (not guess/assume)
Last week I couldn't livestream to Facebook. It wasn't OBS's fault, it was ours in settings selected in creating the Scheduled Event at FB, or FB itself glitching.. not sure really which. A few hours later, I was able to stream.. to a new event...
So, my less than $0.02 is double-check or re-create the stream input settings for reastream.io. Then make sure OBS stream settings match, and try again
