Excel Online Business Connector

When I try and connect to new Excel Online Connector. I immediately get an error The Data did not load correctly. Please try again. Resource not found.

This was all working yesterday the error messages don't really give anything to have a go at.

I am getting the same error. It was working few day ago. and I built an app based on Excel Online

I was having the same issue. I have found that the connector works fine if the document is in a library on a Teams Template Sharepoint. If the excel is stored in a library on a communications site I get the same error.
