Getting errors trying to view a Shiny App

Hi,
I'm trying to view a Shiny app I developed in Python on an enterprise remote development environment but getting serveral errors of the following format:

Refused to execute script from '' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

It's a remote environment so instead of localhost I have to use the platform's proxy address:

 Refused to execute script from 'https://myserver.net/user/myUserID/proxy/lib/requirejs-2.3.6/require.min.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Does anyone know how to get around this?
