Configuration items are missing and the Page is blank. First try loading the configuration page in a different browser to make sure this is not a browser issue. If the page still will not load, this can occur when the Service Credentials are not able to establish a connection with your Dynamics 365 system. This could be a result of expired credentials, or Missing Privileges on the service credentials.
