Where we can find error log for Episerver Admin section error? What is causing error for when we click on link within Episerver Admin tools settings?

Hi,

If any of the link within Episerver Admin -> Tools -> Setting item loads the page just fine and if we select any value and click on button within page it gives "page not found" error in integration DXC environment and works just fine in local environment.

Where we can get what is that causing error for this in Episerver Admin section?
