Troubleshooting

Find the symptom and follow the link.

A domain does not resolve or serve the space: run sf domains check and sf domains diagnostics, then fix the records diagnostics reports. See Verify DNS and SSL.
The homepage is missing: the folder or zip needs index.html at the root. See What serves the homepage.
An upload or finalize fails: retry the publish. A publish rejected over the storage quota does not affect the live site. See Retention and storage.
A bad publish is live: promote a known-good version. See Promote and roll back.
A version URL asks for sign-in: the live URL is not affected. See Permanent version URLs.
Every page asks for a password: space password protection is on, and Spacefast rejects _headers Basic Auth. See Control who can visit.
The CLI misbehaves locally: sf doctor checks local state, auth, API reachability, and the current space link.
