Proxy not working with Proxifier
When using proxies on Proxifier, you need to make sure SOCKS proxies are being used. In the case of HTTP/HTTPS proxies, Proxy Checker will give you an error message
When the SOCKS5 proxy is used, the connection will be successfully completed.
Even after successfully completing the test, the proxy doesn't work, make sure the proxy IP is selected under the "Proxification Rule"
