Cannot tunnel through proxies. Proxy returns HTTP / 1.1 503 Service Unavailable

Question

I want to connect to an intranet server, the url I need to connect is:

URLConnection conn = new URL("https://mywebsite").openConnection();

When I get to the connection method call, do the following: `

conn.connect();

I get the following exception:

java.io.IOException: Unable to tunnel through proxy. Proxy rerurns HTTP/1.1 503 Service Unavailable"
at sun.net.www.protocol.httpHttpURLConnection.doTunneling

How can I solve this exception, I have tried many solutions posted online but with no luck.
