Warehouse Fabric GUI does not update

Hello Alexander_Faber ,

Thank you for reaching out to the Microsoft Fabric community forum. The error you're seeing indicates a timeout issue in the Fabric UI, while Azure Data Studio is functioning correctly. Also thank you nilendraFabric  for your inputs

To fix this, try manually refreshing the schema by going to Warehouse > Manage Tables > Refresh Schema. If your queries are large, they might be timing out before completion, so consider breaking them into smaller parts for better performance.

If you're using Power BI, increase the Command Timeout in File > Options & Settings > Options > Query Execution. Additionally, try pausing and resuming the warehouse from the Fabric UI or reconnecting the SQL Endpoint via Settings > Manage Connections > Reconnect SQL Endpoint.

Check your Fabric capacity and resource limits, as heavy workloads can cause timeouts. If the issue persists, verify the Fabric Service Health Dashboard for any outages.

I hope my suggestions give you good ideas, if you need any further assistance, feel free to reach out.
