Trouble starting a dashboard, HTTP Error 500

Hello, we’ve run into this problem before but I can’t recall what the fix was. Has anyone else experienced this?

When starting UD, the server seems to start normally, no errors. But when trying to browse to the dashboard I immediately receive an error 500. This is true for our custom dashboard as well as an empty dashboard.

With verbose logging enabled we can see the following when sending a request to the server:

[Error] Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingProvider An error occurred while reading the key ring.

Hi

did you solve this issue? i have the exact same issue.
Or does anyone else have a solution?

regards Nathan

Did anyone find a solution to this? I now randomly have this problem after UD working for many months locally it now won’t run any dashboards.

[Error] Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingProvider An error occurred while reading the key ring.

Bit of an old thread but this might help someone if they have this in the future. I had the same happen again on my PC. After spending a day trying various things I think this is to do with having Powershell Universal on your machine (even if you have uninstalled it). After uninstalling it I had to go through and remove all the files/folders from appdata and program data then running v2.9 of UD locally worked!
