Data Monitoring / Power BI Refresh & Data Reliability
Power BI: Expired source credentials
Scheduled refresh stops after a password rotation. Correlate the first authentication failure with credential changes and identify the actual connection owner.
Environment and inputs: Power BI Desktop and Power BI service; gateway, connector, capacity and license capabilities depend on the deployed configuration.
Failure scenario
Scheduled refresh stops after a password rotation. Confirm the cause before choosing a fix.
Evidence to collect
Correlate the first authentication failure with credential changes and identify the actual connection owner. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Update the intended managed connection and verify the next unattended run rather than only a Desktop refresh. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for expired source credentials using the same scope and a representative interval. Check that the symptom is resolved, expected records are present and downstream results are correct. If coverage, correctness or latency worsens, restore the recorded configuration through the agreed rollback process.
Scope and precautions
Prefer read-only access and limit queries to the relevant period or dataset. This example has not been tested on your systems. Test changes in an approved environment. Keep credentials and sensitive data out of shared evidence.
