Custom Teams App not loading under macOS

Hello,

 

we are developing an app for microsoft teams where we have a new tab in meetings. But we are struggling to get it working under macOS. When we upload our custom app and add it to a meeting, nothing shows up and according to the tcp dump the connection to our app is refused due to an unknown certificate. The app works fine under windows and is reachable in the browser.

 

We have a custom domain thats pointing to a reverse proxy that is forwarding to our company on-prem k8s.

 

Do you have any idea how to fix this problem? Has anyone encounterd something similiar? Any ideas how to investigate this issue more deeply?

 

Any help is welcomed.

 

Best regards

developer

      nautalis - Could you please let us know if it is happening in Teams Classic or New Teams? Also, if it's happening in Teams desktop or web client? Please do share the manifest file as well which you are using.

        Prasad_Das-MSFT The issue is happening on both Teams Classic and New Teams on all deployed macOS laptops. The custom Teams app works fine through web client on macOS. The custom app is installed via app policy. The custom app does not present any error windows, messages, or feedback. When clicking on the custom app, all the user sees is a blank white screen in the right-hand pane. What the user should see is the organization's intranet SharePoint site.
