Failed to load resource: Server responded with a status of Error 401(Unauthorized)

[Cyadav]

While viewing the dashboard/Report on PBI Report Server, we are getting some unauthorized Error 401, while viewing the source by pressing F12 key. Any suggestion/Feedback to overcome with this error. Eventhough it is not impacting the working of dahboard but might be page loading is slow because of this issue.

It didn't work, even after following your instructions, same error. Any other alternative for try, please suggest.

Hi, @Cyadav 

I don’t know your situation, it’s hard to judge if there is only one error screenshot.

So can you describe more information, like I asked you in the last reply?

Check if the firewall blocks the TCPIP port.

Hi, @Cyadav 

Are there any errors in the report? Is there anything unusual in the map visual? 

You can try to publish the report to report server again or clear the browser cache and try again.
