For certain types of errors when authorizing from Swagger UI, it is difficult to see why the request fails, see for example this:
Inspecting the request which was issued, it's clear that the Authorization Server actually responds with a leading error message, e.g. that the application is not declared as confidential, or similar.
This is related to swagger-api/swagger-ui#4048; I have filed a PR on that repository to get more information back in case of failures when talking to the /token end point.
