Authorization troubleshooting
If the sign-in window closes right away, shows an error before you finish, or every retry gets stuck, the cause is often a broken OAuth session on the provider side (Google, Microsoft, and others). The steps below fix many cases without contacting support.
The authorization window closes immediately or shows an error
Symptom: you click Sign in in Latenode, the provider pop-up opens and closes almost instantly (sometimes with an error). You cannot complete a new authorization; the same error happens when you reuse an existing one.
Why: a previous OAuth attempt may have been interrupted (closed window, network, browser extension). The provider may block further sign-ins until app access for Latenode is revoked in your account settings.
What to do:
- Open your provider account settings (not Latenode), for example Connected apps, Third-party apps, or Apps with access to your account.
- Find Latenode (or the app used for the platform OAuth connection) and remove / revoke its access.
- In Latenode, open Authorizations or the node settings again and sign in from scratch, keeping the pop-up open until authorization succeeds.
After revoking access on the provider side and signing in again, authorization usually works.
This happens most often with Microsoft services (Excel, To Do, Outlook, Teams, and others), but the same approach applies to other OAuth providers that list connected applications.
If it still fails
- Try another browser or a profile without extensions (ad blockers often break OAuth pop-ups).
- Create a new authorization with a different name instead of reusing a broken one.
- Email [email protected] with the service name, a screenshot of the error, and note that you already revoked app access on the provider side.
