1. Deliberately release or drop held lab messages; turn Burp intercept off or unset ZAP global break.
2. Clear a manually configured proxy in the dedicated lab browser, or close the browser launched by the proxy.

4. Quit the proxy application.
5. Confirm no listener started for the session remains. If uncertain, stop and record the remaining configuration before using that profile again.
