+### Socks5 Proxy example
+
+- **!This Example only works with socks5 proxys!**
+
+Make sure your proxy connection is working.
+
+#### Testing proxy connections with curl on Unix systems or Command prompt on Windows:
+```bash
+curl -x "socks5://<proxyAddress>:<proxyPort>" "http://ifconfig.me"
+```
+If you see an ip address the proxy is working. If you see anything else it's not.
+
+
+#### These Errors what do they mean????
+```
+FetchError: request to https://authserver.mojang.com/authenticate failed, reason: Socket closed
+```

+
+

+```
+SocksClientError: Socket closed
+```
+- General Socket error Bad Proxy/Proxy refuses the connection
+
+--------
+```
+SocksClientError: connect ECONNREFUSED <some ip address>
+```
+- The Connection to the proxy Failed
+
