Flow fails with 401, worked yesterday
OAuth token or refresh token expired or revoked. Re-auth and check expiry policy.
Try this first
- 1Open connection in flow tool and re-authenticate
- 2Check refresh-token policy isn't shorter than assumed
- 3Use service account, not a personal one
- 4Add monitoring on 401 spikes
When to bring us in
Repeated expiry: ask IdP admin for longer refresh window.
