# Destination shows 'Disconnected' or 'Not Connected'

> A destination showing Disconnected or Not Connected was never fully authorized or the OAuth flow was interrupted. Reconnect it and grant all requested permissions to restore delivery.

**Likely cause:** The destination was never fully connected, or the OAuth authorization flow was interrupted before completion.

**Fix:**

1. Go to **Destinations** and click the affected destination.
2. If the status says **Not Connected**, click **Connect** to start the authorization flow.
3. Complete the full OAuth flow in the popup window — make sure to grant all requested permissions. For Meta, ensure you select the correct Ad Account and Pixel. For TikTok, select the correct Advertiser Account.
4. After authorization, return to Upstack and confirm the status changes to **Connected** (green).
5. Trigger a test event on your store and check the Live Event Stream to verify the destination receives it.

<Note>
  Pop-up blockers can silently prevent the OAuth window from opening. If clicking **Connect** does nothing, allow pop-ups for `app.upstackdata.com`.
