webscan_socks5_proxy_config_failed

Error message

webscan_socks5_proxy_config_failed: %w

What it means

Guard in configureHTTPProxy: the SOCKS5 proxy settings were parsed but proxy.NewProxyManager(...).GetDialer() failed, so no dialer could be constructed for the configured SOCKS5 proxy and the HTTP transport cannot be built with SOCKS5 support.

Solutions

1. Verify the SOCKS5 proxy address, username, and password
2. Test the proxy with an external client to confirm it is reachable
3. Fall back to direct connection if the proxy is optional
