To do this:
1) Open Opera browser
2) In the address bar, type 'Opera:config'. This will bring the advanced configuration panel
3) Scroll down to the Proxy section
4) Disable (uncheck) the checkmark in front of HTTP and HTTPS
5) Save and restart Opera.
This has made my browsing faster and it now works for many more sites, no disconnection, no weird message, etc.
