I was thinking along the same lines.. to test the URL on the server with curl, wget, etc. and to add it to your Safe Domains for 'connect'

My public OAC worked.
My OAS never completely saved. I know why, it is behind a proxy server, so I know I have to use an unsupported "hack" to enable tunneling through the proxy server.
For that part, I was more commenting on the bugginess in the UI that Gianni was mentioning (two issues here).

@Dhaval Parikh Stantec - I don't mind, but it would carry more "weight" coming from a customer with a service request. I was unaware you had one opened already, can you post the SR number here.
