Sharepoint Online Provider Hosted Add-in "Sorry, something went wrong with adding the app.

I have created a very basic SharePoint app to test Remote Event Receivers and installed the application in the Sharepoint App Catalog; I did not receive any issue on that.
When i tried to install the app in the test site i receive the erro below.

I also tried to debug the app from Visual Studio but i still have the same issue

Can you please help me?

Thanks

Masismo

Attached i send you the Appmanifest.xml and the EventReceiver file that i used in Visual Studio for my testing, maybe there are some missing configuration or some issue.

Hi @MassimoMattiello-0365,

You could check the following:

  1. When you test the app in developer site, did everything work well?

  2. If you install the app in other sites, can you reproduce this issue?

  3. You could hover over the app to check the error details.
