Swagger 401 undefined /resources

I have enabled swagger on my services but when browsing to the /swagger-ui/ link I get presented with the following error:

401 : undefined http://localhost:52979/resources

Pretty certain I am not blocking this request? Any ideas where to look?

Looks like something is interfering with the Request, do you have anything called Resources, e.g route, file, folder, etc?

:ok_hand: Good catch Demis thanks.
