Answer 4

This Status Code 500 is an Internal Server Error. This code indicates that a part of the server (for example, a CGI program) has crashed or encountered a configuration error.

HTTP status code 500 usually means that the webserver code has crashed. You need to determine the status code beforehand using HttpURLConnection#getResponseCode() and in case of errors, read the HttpURLConnection#getErrorStream() instead. It may namely contain information about the problem.

If the host has blocked you, you would rather have gotten a 4nn status code like 401 or 403.
