Note:

If the error "unable to connect to the remote server" is reported and can be accessed through a browser, you must have missed this sentence, as shown below.

Request. Proxy = new WebProxy ("sinproxy.southpacific.corp.microsoft.com ");

To access the URL through a browser or your own code, make sure that the environment is the same.
