Connection with Momence keeps failing

Hello, I teach online classes over zoom and I have an API set up with Momence to provide both myself and my students a unique zoom number for each class, but the connection has refused to work for the past month. I transitioned over to the server-to-server oauth from the JWT app, but I still haven’t gotten it to work. The team at momence has also tried helping on their end, but the zoom API randomly disconnects and it is making it very difficult to host my classes. Please provide assistance.

Please note I am absolutely not a developer so please provide assistance in layman terms…
