Ok. I tried plugging into Ethernet and thought that would fix it and it still didn’t work. Ugh... I’m going back tomorrow to test again. I’m not sure what to do especially for future events where I can’t access their router. Tomorrow I’m going to check my IP address setup and DNS
I may have figured it out.
I’m using a Thunderbolt adapter for Ethernet. I had to go to Settings > Sharing > Internet Sharing and turn on the adapter.. I switched the ATEM to DHCP and it worked.
I’m still a bit nervous now to use this on location though...
