Issue:
Url_response probe shows "Couldn't resolve host name" for every url when i click "TEST"
The same URL's work on browser on the same machine. The browser resolves the URL's while the probe cannot.
Environment:
url_response 4.x
Cause:
Most likely a proxy is configured on the machine hosting the probe. You can also verify that by trying resolving the url on the command line. If you cannot resolve the the URL from command line but can navigate to the URL using a browser, then most likely there is a proxy in the middle. 
Resolution:
The probe supports proxies and user authentication for accessing the requested web URL. 

Configure the proxy as described in the probe documentation
