So, is your local TOR service running?

If you can't see something like this, you're not going anywhere.
TCP 127.0.0.1:9050 0.0.0.0:0 LISTENING
I assume you've read this

salem_c I tried Port Listener and now I'm getting an error:
Port Listener showed that I was connected and then disconnected. I also tried Privoxy before but it didn't work for me. I also tried this code on Windows 7, and I got the same error as default by using this code.HTML Code:[*] C++ Tor[*] Connecting[*] Error Authenticating
So what is the return value from the send() and recv() just prior to the error message? If these aren't 'good' return values, what is the error code?
I suggest you change this code so that the return value from every API is checked for 'good' and if not good, then the error code is displayed along with a message indicating which API caused the error. You'll need to check the API documentation to determine for each API what is a 'good' return value.
Do you mean this? std::cout << "[*] Error Authenticating " << WSAGetLastError() << std::endl;? It's[*] Error Authenticating 0, it exited with code -1.
WSAGetLastError does NOT return code -1. It can return only the codes mentioned here.Quote:

Post your latest code here so that we can have a look at it. Don't forget to use code tags.

This is what I'm talking about regarding checking return values from every API:
This compiles for me for MS VS 2019. Compile and run this and see what error message it generates. You will know which api is causing the issue and why.Code:#define _WINSOCK_DEPRECATED_NO_WARNINGS

Error Authenticating Resp1. It seems like Resp1 is failing.
Well, you now know 2 things 1) The prior API calls are not failing and 2) that the preceding recv() is actually receiving data (as Resp1 is now initialised to 0 before and then tested for not 0 after).
Have you tried commenting out the Resp1 test so that the code gets as far as fetching?
