Swagger + NGINX Plus configuration, wrong base url

We have migrated to NGINX Plus as Ingress controller, and seems that the base URL is not taken correctly

I start swagger using https://uosd.toyota-europe.com/uos-web/swagger-ui.html, but when I see the base URL inside the console it shows met the upstream URL and not the original one anymore. 

Wondering where swagger is taking this one from?
