Error messages in deployment overlay is not always correct

[nithinssabu]

Describe the bug

The errors messages related to connection check is not always correct in the deployment overlay. Here are two examples of incorrect error messages:

1. If a wrong Client ID is entered, the error message is “Should point to a running OAuth service”, whereas I would expect to get wrong credentials message for Client ID and Client secret.
2. If a wrong value is entered for Audience, then the error messages for Client ID and Client secret is shown.

Steps to reproduce

Case 1:

1. Enter valid values for all fields in the deploy modal

Case 2:
