ATEM Mini Pro output to YouTube and FaceBook not working

I have an ATEM Mini Pro. I have a problem outputting directly to YouTube and FaceBook. I made sure that my stream keys are correct, but I can’t seem to get it to work on either platform. It works find as a “webcam stream” on both. Any tips, tricks or suggestions?

How are you connecting the ATEM to the Internet? I was sharing an internet connection on my laptop, but found this less than 100% reliable. I have just bought a travel modem switch to test to see if that makes it more seem less and easy.
