Power BI Service may experience gateway connection issues while refreshing reports. Besides, the primary causes of the issue and troubleshooting steps to recover the problem have been provided. Therefore, the following is a remedy for the above problem for proper understanding:
- Gateway Connection Failures and Their Common Causes or Troubleshooting Solutions
Network And Connectivity Factors: Power BI mandates a solid network connection that connects the data sources to the gateway. Network issues whereby there are downtimes of the network, firewall configuration blocking the gateway, or even the VPN services being mixed up can cause connection problems.
In The Connection Or Gateway Configuration Problems: It is possible that the gateway was properly installed; however, data refreshes may fail due to wrong data sources not being configured within the gateways, using an old version of the gateway, or access rights being denied.
High Demand For Resources On The Gateway: This can also happen when the on-premise data gateway is busy handling large amounts of data, or it is running on a machine with very low specifications. Resource limitations can also cause the interactions between the servers to fail. Overusing the CPU or RAM of the server where the gateway is hosted may also lead to connection failure.
- Troubleshooting Issues with the Gateway
Cross-out Network and Firewall Settings: Assure the gateway is properly connected to the Internet and confirm that no firewall/security rules are placed on Power BI's needed ports (usually 443). Confirm that no VPN restrictions will prevent the gateway from reaching its data sources.
Reinstall the Gateway: Make sure the on-premise gateway is up to date with the latest version. Microsoft often issues updates that enhance and extend its capabilities. You can always get the newest version from the Power BI service or Microsoft's website.
Check Data Source Credentials: In Power BI Service, navigate to the dataset settings and ensure that all data source credentials are accurate, including their expiry date. Refreshes may fail to proceed due to missing or overdue credentials.
Oversee Gateway Resource Utilization: On the server that runs the gateway, open the Task Manager (Windows) and monitor CPU and memory resources. If resource usage is high, the data load should be lessened, hardware upgraded, or queries improved to reduce it.
- Actions to Ensure Dependable Gateway Connections
Systematically Plan Refresh Intervals: To minimize the chances of encountering connectivity challenges, plan data refresh activities for periods of low network usage. Scheduling intervals for refreshing times can also avoid overworking the gateway.
Form Gateway Groups: If the situation is likely to require many gateways, it would be wise to set up a gateway cluster. The load is shared among the individual gateways, preventing complete failure and increasing the reliability of refresh operations.
