An error occurred while processing the semantic model

Hi ManasRout0396​,

Thank you for reaching out to Microsoft Fabric Community.

The error indicates that the gateway was unable to establish a connection to the data source within the allowed time. This could be due to temporary data source slowness, network connectivity issues or gateway resource contention.

Since multiple reports are affected, please check whether they use the same gateway and data source. And check gateway CPU/memory, overlapping refreshes and source availability at the failure time. Also, verify whether the data source was reachable from the gateway machine when the refresh failed.

Try refreshing one affected model outside the busy period. If it succeeds, then this can be a transient or load-related issue.

This will help identify whether the issue is related to gateway connectivity or the underlying data source.

Thanks and regards,
Anjan Kumar Chippa
