How to fix "Error: Proxy server got bad address from remote server (verify the server is running" in ArcGIS Server?

Question

I am trying to connect ArcGIS Server in ArcGIS for Desktop. The connection type is Publisher connections (Public GIS Services). After I put all info about Server URL and authentication,  I got the following Error Message.

"Server URL (in this case, our particular server URL)

Error: Proxy server got bad address from remote server (verify the server is running). "

Running Fiddler when you're trying to connect may help.  It'll tell you if there are any HTTP errors.  If your Server is federated, make sure you use a publisher or admin account within the Portal.

Thanks for the info.  I'm certain I have the right instance name so I'll keep looking.

Keith,

As far as I can remember correctly, I think I was typing the instance name wrong.
