Power BI report server October 2020 - hanging issue & 401 (Unauthorized) error

AsilAllaham — Tue, 24 Nov 2020 06:50:23 GMT

Hello,

I need help in understating the cause of the following issue:

While using a Power BI report deployed on Power BI report server the report goes into a hanging state (I just get a loading message on the web page) when refreshed and few times the charts used in the report after refreshing the report through F5 gave me an unexpected error message.

* Please note: that the report has a tabular model in direct query mode as a source and this model was connected to an oracle database using oracle oledb conector.

While tracing the issue I saw the following errors in chrome consoul:

> GET http://10.105.4.27:88/Reports/assets/img/fi/pbirs/manifest.json 401 (Unauthorized)
* Manifest: Line: 1, column : 1, Syntax error.
* GET http://10.105.4.27:88/Reports/assets/img/fi/pbirs/manifest.json 401 (Unauthorized)

(Internal Server Error)

and at the same time thiss error was loged in RSPowerBI_2020_11_10_09_39_33 logfile:

Hi, @AsilAllaham ,

Did you have this error before your report server upgraded to PBIRS (Oct-2020) version?

Hi @DavisBI ,

Yes, in August 2020 I was tasked to build a report on the server on which the issue appeared on. And it had PBIRS Oct-2017 version, so to use the latest version back then I upgraded it to the August-2020 version, I only had one user the admin user, and the report building and deploying process back then worked smoothly.

Moving forward on 09-11-2020 I added a local user that had access to the report, then on 10-11-2020 the issue appeared and I thought that it may be a bug in the Aug-2020 version so I upgrade it to (Oct-2020) and the issue did not go away.

I appreciate your help.

Regards,

Hi @AsilAllaham ,

What's your verification method? Custom authentication? How about swtiching back to windows authentication? Maybe this is the cause.

In addition, is this the case for all reports?

Best regards

Hi Icey,

I used windows authentication {as the user viewing the report} and to answer your second question the server only continued the report which I created and honestly, I did not create any other report to test upon.

Best Regards,
