Impala Power BI Service Refresh Failing

Okay I saw SASL in your third screenshot that means you are using Cloudera on-prem.

There can be more than one reason about these fails. I suggest you to check CPU and RAM of your Server. Also check the log file from here:

C:\Users\PBIEgwService\AppData\Local\Microsoft\On-premises Data Gateway\Gateway.log

If memory is near 100%, this explains error in your first and second screenshot.

For your third error, if you are using Service principal then check if password expired, if service principal user is still valid and impala access of this account.

If this solved your issue, please mark it as the accepted solution. ✅
