SmartBear App showing 'Error: Server error.' on credential submission

I am able to login to the website with my credentials but when I try to start the app and use the same credentials, I am seeing an error message :Error:  Server error.  Under the Security Center tab on the account details, I also found a reference to the API key and a tried to use that as the password field paired with the Login but get the same result.

UPDATE - I tried the process again today and it connected when the web app started...  No idea what changed but this problem is solved.  I don't see a place to close my post.
