"Invalid scheme" error when importing HTTP/HTTPS proxy lists

I’m trying to paste a list of proxies from my provider into the Stealth tab. The format they gave me is ip:port:username:password.

When I click “Test Proxies”, I get an “Invalid scheme” error. Do I have to manually reformat 1,000 proxies?

No need to reformat them manually! Our proxy parser is designed to handle both standard URL formats (http://user:pass@ip:port) and the legacy format your provider gave you (http://ip:port:user:pass).

The error you are seeing is because the parser requires the protocol scheme at the beginning. Just do a quick find-and-replace in your text editor to add http:// to the start of each line, paste it back in, and you’ll be good to go.

Pro tip: Use the built-in “Test Proxies” button. It actually pings an external IP checker through the proxy to verify that your real IP is successfully hidden before you start your scrape.
