Lovable GitHub Sync Not Working

How to fix it

Try these in order — the most common fix is first.

1. 1. Reconnect the workspace connection

   Copy steps
   1. Open the project's GitHub settings
   2. Click Reconnect; one fix typically restores every project on that connection
   3. If the app was uninstalled, reinstall it; previously synced projects need new repositories
   Did this fix it? Yes No

2. 2. Sync the right branch

   Copy steps
   1. Lovable syncs one branch at a time, usually main
   2. Use the branch picker or merge your commits into the synced branch
   3. If a push was missed, push a new commit (even an empty one) to the synced branch
   Did this fix it? Yes No

3. 3. Check for rejected pushes and deleted branches

   Copy steps
   1. If branch protection rejects a push, Lovable pushes to a lovable-sync branch: review and merge it
   2. If the synced branch was deleted, Lovable switches to lovable-fallback
   Did this fix it? Yes No

4. 4. Remove oversized files

   Copy steps
   1. Find files over 100 MB and remove or shrink them
   2. Push again
   Did this fix it? Yes No

5. 5. Disconnect and reconnect as a last resort

   Copy steps
   1. Disconnect in project GitHub settings (the repo stays on GitHub)
   2. Connect again; this creates a new repository because linking an existing one is not supported
   Did this fix it? Yes No

Symptoms

Commits pushed to GitHub do not show up in Lovable, Lovable changes do not reach GitHub, or the connection shows an error.

Why it happens

• Repository deleted or moved
• Commits pushed to a different branch than the one Lovable syncs
• Push rejected by branch protection
• Files over 100 MB blocking pushes (Lovable also cannot edit files over 10 MB)
