Gmail trigger not responding

I created a Gmail new mail reading flow in n8n, and it had been working fine for the past 6 months. However, since August 6, 2025, n8n has stopped reading emails automatically. When I run it manually, it works, but the automated trigger is not working.

I’m using a self-hosted n8n instance because I’m reading a company email. Please help me resolve this issue.

Note :

  • No any email password updated
  • No any other credentials deleted from google console

Pleas help me

Hi @Manish_Mundra

welcome to the community! if your Gmail Trigger stopped firing since Aug 6, it’s usually one of these: the Google token expired (open your Gmail credentials in n8n, click reconnect/re-authenticate, save, and reactivate the workflow), rate limiting (set the trigger to poll every 5–10 minutes and mark processed emails as read/remove label), the workflow isn’t active (toggle it to Active), or API/scope changes (in Google Cloud, make sure the Gmail API is enabled and your OAuth scopes/service account delegation are still valid). quick fix order: re-auth creds → set 5–10 min polling → ensure Active → verify Gmail API/scopes.
