Prepare the client
Use a current cURL installation. Replace the proxy host, port and username; the client prompts for the password.
Connection example

--max-time 30 \
https://example.com/Verify the connection
Start with a public test destination you are allowed to access. Confirm authentication, exit IP and timeouts before adding target-specific parsing. Never disable TLS verification to make a failing connection appear successful.
When it fails
Review Troubleshooting for authentication, DNS, connection and TLS errors. Include your client version and a sanitized error when contacting support.
