Hi,

When trying to open Dashboards, I'm redirected to sign in to https://<dmaip>/auth/login , I'm getting "An unknown error occurred (status:500)" after filling in my credentials. I am able to connect to the DMA with DataMiner Cube.

How can this be further investigated? Which log files can be consulted?

Regards,

Found the issue. For those who might have the same problem:

Windows event viewer, Application log showed the exception that Skyline.DataMiner.Web.Global could not be loaded.

This issue was happening because I downgraded to 10.5.7, where this type is not known yet.

Removing C:\Skyline DataMiner\Webpages\API\global.asax file and performing an iisreset command fixed the problem.

We also saw this error with upgrading from 10.5 CU0 to 10.5 CU5 which the solution mentioned by Laurens also fixed.

Hi Laurens,

There are a few things you can check:

  • Open the devtools and check for console errors & failed network requests.
  • Check the WebAPI logs at C:\Skyline DataMiner\Logging\Web.

If these do not give any clarity, I suggest you reach out to techsupport (support@dataminer.services) to look into this further.
