+title: Receiving an `authentication has expired` error when trying to run queries in the IDE.
+description: "Reauthenticate warehouse when seeing `authentication has expired` error"
+sidebar_label: 'Receiving `authentication has expired` error in the IDE'
+---
+
+If you see a `authentication has expired` error when you try to run queries in the dbt CLoud IDE, this means your [OAuth](/docs/cloud/manage-access/set-up-snowflake-oauth) connection between Snowflake and dbt Cloud has expired.
+
+To fix this, you'll need to re-connect the two tools.
+
+Your Snowflake administrator can [configure](/docs/cloud/manage-access/set-up-snowflake-oauth#create-a-security-integration) the refresh tokens' validity, which has a maximum 90-day validity period.
+
+To resolve the issue, complete the following steps:
+
+1. Go to your **Profile settings** page, accessible from the navigation menu.
+2. Navigate to **Credentials** and click on the project you're experiencing the issue with.
+3. Under **Development credentials**, click the green **Reconnect Snowflake Account** button. This drives you through reauthentication through the SSO workflow. 
+
+If you've tried these step and are still experiencing this behavior, reach out to the Support team at [email protected] for further assistance.
