Unable to apply API permissions to App Registration

Question

Attempting to apply API permissions to an App Registration results in the below error. Anyone have experience resolving this or do I need to wait on support from MS? I've cleared the cache, rebooted, tried incognito. I've had other GAs within our organization attempt as well, they get the same error.

Answer 1

To resolve the issue "Network error: There is an issue establishing a connection to the service. Please refresh the browser to try again" please try the below:

• Make sure you and your users have a subscription for Dynamic CRM. Users without the subscription may not be able to access of the features.
• Make sure your network has strict Security Policies/ACLs.
• If you are trying from co-operate network and facing the issue then there might be some filtering configured on your network.
• Try changing the network.
• Collect a network trace or browser trace to check if some requests are getting dropped.
• If the issue still persists, try to use the developer tools provided with the Edge Browser and see if you get any errors.
• Make sure you don't have any browser extensions enabled that could interfere with your traffic.

I tested in my environment, and I am able to add the permissions.
