I know that there is no proxy set up, but I do not know how to effectively set up a useful server address and port. Mainly do not know how to replace the 'myproxy.example.com:1080/' value, ask whether the proposal in this regard.

I am grateful for any and all recommendations

Best regards,

Kelvin
