Volt problem - error message in browser just started

Myself and another student are having a problem that just started. We are deploying to Volt server. We deployed it several times. On the popup that comes up, when we click on the top url, it goes to this page:

But if we use the QR code, it works on the iphone.

This is what the Preferences show:

It worked fine until it didn’t. Thoughts?

I tried it here using my account - it’s fine, so it looks like something with your app.

In Project Properties, in the VoltServer tab, there as a property called Appid. Can you tell me what that value is?

I don’t know what the student’s is, but mine (which was doing the same thing) is BBCewo.
