Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error: This message is sometimes displayed when accessing an SSL page via a proxy
It is caused by Chrome being unable to render the 502/302 proxy response for some sites
You can try the proxy with a different port than 80 (our proxies are also working on port 55555)
If that isn’t possible you can try with this:
Check your browsers Proxy settings.
To change this setting, go to chrome://chrome/settings/
Then Click [Show Advanced Settings]. Scroll down to [Network] and click [Change proxy settings…] Uncheck Automatically Detect.
