Lovable Not Working? Common Errors & Fixes

Lovable spends credits on build attempts even when the result is an error. Use the free Try to fix (10 free uses, each back after 24 hours), investigate in Chat or Plan mode first, and email support for outage-related losses.

Lovable can keep introducing new bugs while fixing old ones on complex features. Stop prompting build fixes, use Chat or Plan mode to diagnose, break the work into smaller steps, or revert.

When plan credits run out you can buy one-time top-ups, enable auto top-up, use daily credits, or upgrade. Top-up credits last 12 months and monthly credits roll over until they expire.

Most GitHub sync failures are a suspended or uninstalled Lovable app, a deleted repo, or commits on a branch Lovable is not syncing. Use Reconnect in project GitHub settings, or push a new commit to the synced branch.

The Supabase connection issue message usually means the linked Supabase project was deleted, paused, or your access changed. Disconnect or manage organizations in Lovable, and confirm the project is active in Supabase.

A Lovable custom domain needs a published project, correct DNS records, and no conflicting CAA records. Use Check again in Domains settings, and contact support if the SSL certificate is not issued after 72 hours.

Sign-in failures on a new Lovable domain usually mean the domain is missing from the auth redirect URLs, and from the OAuth provider's allowed redirect URIs if you use social login.

Edits in Lovable go live only after you publish an update, and browser or DNS caching often hides a successful publish. Click Publish, then Update, verify the latest publish succeeded, and hard refresh.

Missing row level security policies are the most common cause of exposed data in Lovable and Supabase apps. Make sure every table has policies limiting who can read and write each row, and verify them in the Supabase dashboard before launch.

A stuck Lovable preview is usually a build error or a platform issue. Use Try to fix once, investigate in Chat or Plan mode, revert to an earlier version, and check the status page before spending more credits.

Cancel Lovable from Workspace settings, Plans & credit usage, Manage, Downgrade to free. Your plan stays active until the billing period ends and the current period is not refunded.
