HTTP proxy check

curl -x http://LOGIN:PASSWORD@PROXY_IP:PORT -I https://www.google.com

Example with real data:

curl -x http://KWFFEKf:[email protected]:44454 -I https://www.google.com

SOCKS5 proxy check

curl --socks5 LOGIN:PASSWORD@PROXY_IP:PORT -I https://www.google.com

Example:

curl --socks5 KWFFEKf:[email protected]:44454 -I https://www.google.com

How to interpret the result

The proxy works. If in the response you see HTTP/1.1 200 OK or HTTP/2 200, the connection was successful.

The proxy does not work. If you get an error like Connection refused, Connection timed out or Could not resolve proxy, then the connection could not be established.

What to do if it does not connect

1. Double-check the login, password, IP, and port. A common mistake is mixing up HTTP and SOCKS5 ports

2. Try connecting through a VPN to rule out blocking by your provider

3. Wait 2-3 minutes after purchase: the servers need time to update

4. If nothing helped, contact support
