When a rotating proxy cannot connect, first check the generated result, authentication mode, and source network.
Key points
- Confirm the host, port, protocol, and proxy connection credentials.
- In whitelist mode, confirm that the current public egress IP is authorized and active.
- Generate new connection details to rule out stale parameters or sessions.
- 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.
