+## Timeout errors
+
+### Problem
+
+Executing calculations within the notebook returns a timeout error after a few minutes.
+
+### Cause
+
+The Distributed Data Lab cluster has zero worker nodes provisioned and cannot raise any resource to perform the required operations.
+
+### Solution
+
+[Edit your cluster configuration](/managed-services/data-lab/how-to/manage-delete-data-lab/) by provisioning at least one worker node to be able to run calculations with it.
+
+<Message type="note">
+You can provision zero worker nodes again to retain you cluster and notebook configurations while minimizing its cost.
