Springfox Swagger returning HttpMediaTypeNotAcceptableException

I configured SpringFox Swagger in my Spring Boot Application. I am seeing HTTP 406 (HttpMediaTypeNotAcceptableException) when I try to access "http://localhost:8080/swagger-ui.html"

This post helped me. I had extended WebMvcConfiguration for adding cors configuration which was interfering with springboot auto configuration. I removed the class which had WebMvcConfiguration and this resolved the issue.
