What is meaning of «sending request to protector server error (3-3, #0)»?

 

While through some service providers, my computer is connected to the Internet, at the time of compiling, this error is observed and the compiler stops.

Where I clicked to compile

«sending request to protector server error (3-3, #0)»

But when we change the provider, this problem doesn't happen anymore.

Even if I don't change the service provider but create a VPN connection, the problem will still be resolved.

Why?

What is this error caused?

Why isn't this error explained in the list of cloud compiling errors?

 
Can anyone propose a viable solution to this issue?
