Looking for an Actual Allow List for App Inventor

Would someone please share the allow list for App Inventor. I cannot find a good one anywhere on the web. Our content filter has all the URLs allowed, but our firewall is blocking IPs and not sure which ones are related to App Inventor. This seems to be causing the error to stop the AI companion to loading at 20% that others are having. I think we are hitting the TURN server, but not really sure. I see this IP for sure is one, 128.52.137.132 with several random ports.

And maybe these ones?
142.251.2.127
174.208.104.69

This may help. * School IT/Network Admins: Information specific to school networks (also helpful for conferences and hotel situations)

Someone from MIT will post here about a complete list of url's

Here are a few:
