So I Have 2 servers that run Ubuntu 20.4
One of them I can easily make socks5 proxy without any problem.
The other one I can't, even if I allow ports in the firewall with ufw allow [port], I use 3proxy that works great on the other server.
I check proxies with Proxy checker (Proxifier)
checker error:
[19:33] Starting: Test 1: Connection to the Proxy Server
[19:33] IP Address: my IP
[19:33] Connection established
[19:33] Test passed.
[19:33] Starting: Test 2: Connection through the Proxy Server
[19:57] Error : connection to the proxy server was closed unexpectedly.
Please make sure that the proxy server protocol and address are correct.
[19:57] Test failed.
[19:57] Testing Finished.
And here are my curl logs
curl -i --socks5 IP:1080 --proxy-user user:pass google.com --socks5-hostname localhost
