## Updates from MongoDB Atlas

Users of Atlas Data Federation and Online Archive using cloud-provider IAM authentication may see pipelines fail with an error when querying backing Atlas clusters. Other authentication methods are unaffected. As a temporary workaround, users can use SCRAM authentication.

### 2026-07-09 10:57 UTC: identified
We have identified that the issue is caused by a recent configuration change to IAM authentication and are working on a fix.
