502 bad gateway when deploying to AWS, works locally.

Im using 2.9.2 version of the springfox-swagger-ui and springfox-swagger2.

I added a dist of swagger to do some customisation, replaced the petstore parts with window.location.origin + "/v2/api-docs" in a variable in the JS files (not the map files). It works fine locally but when deployed on AWS I have this unable to infer base url error.

Anyone knows what the issue is about ?
