Quick answer
PuTTY -cleanup is a broad local reset that can remove saved sessions and trusted host-key records. Prefer deleting one obsolete session when that meets the need.
Applies to
For the owner or an authorized editor of the website/account named in this article. Confirm the installed product version and permissions. Interactive Online hosting access does not automatically grant an application administrator login.
Steps
- Use your own authorized computer and obtain the correct hosting connection details. Keep private keys and passphrases outside chat and website files.
- Preserve needed session information and review the official cleanup documentation. Use the official executable with -cleanup only for an intentional full local reset.
- Reopen the saved-session list and check that only the entries you deliberately removed are absent. Keep any required connection details recorded securely.
Check the result
Confirm the actual host, account and intended setting, rather than relying on a saved label.
Troubleshooting and support
For a changed host key, permission error or missing setting, confirm the service details and supported application version. Do not bypass certificate/host-key checks or expose an SSH listener publicly.
Contact support from the owning account with the domain, product/version, exact error, time/time zone and redacted evidence. Exclude credentials, session URLs, payment details and private customer records. Confirm any separate application-support scope.
