Gmail Connectivity Issue

[Rochelle Schupbach]

Hi folks. I'm unable to connect Trello to my Gmail. When I try to download the app, I get to this page:

And then get this error:

I've tried the usual restart, signout/signin, clear cookies, etc. Any other ideas?

Thanks!

Hi @Rochelle Schupbach ,

This issue is most likely caused by your browser blocking third‑party cookies, which can break the OAuth install/consent flow.

Please try the following:

1. Open Gmail in an incognito/private window or a different browser, then try connecting again.

2. If it works there, the problem is usually a browser extension (like an ad/tracker blocker) or a strict privacy setting.

3. Go back to your normal browser, temporarily disable those extensions, and try the connection again. You can re‑enable the extensions once the setup is complete.

Hope it helps 🙌
