I can't set up the messenger.

I set everything up according to the instructions, but there's no connection. This is what it shows:

Could this be a problem on Cloudflare's end?

Is this the Messenger Flutter app?

I don't think it'll be Cloudflare. It's possible a misconfiguration or API key of some sort. I don't really use the messaging app, so I don't have a great amount of experience with it.
