ADFS – SAML endpoints is configured but says otherwise

  adfs, single-sign-on, windows

I’m trying to get the testing environment to work with ADFS & SSO.

My understanding of the problem based on the error message is that the endpoint is not configured, which it is.

Identifier: customer1.testing.companyX

Endpoint: api.testing.companyX/api/samlGoogleResponse

Error on Server Manager

What the hell is missing?
