When a rotating proxy cannot connect, first check the generated result, authentication mode, and source network.

Key points

  1. Confirm the host, port, protocol, and proxy connection credentials.
  2. In whitelist mode, confirm that the current public egress IP is authorized and active.
  3. Generate new connection details to rule out stale parameters or sessions.
  4. Test another location or endpoint and check firewall rules.

Note: If it still fails, provide support with the error, test time, and connection format with the password redacted.
