Icons not showing when deployed locally but works on Studio Pro

  App is deployed to IIS and tested running but there is a problem with the icons. It doesn’t show up. but my pre uploaded images are loading (ex. the Big X).  What can be done ?   I know how to troubleshoot websites and their errors using browser console but websites made by Mendix cannot be reached by my understanding yet.   Thank you in advance :)

This is a very late response but hopefully this helps someone else in the future.

So, IIS won't server a file-type it doesn't recognise. Your issue is regarding the woff filetype and you will have to simply add it as a mime type in IIS. to map extension woff2 to type font/woff2 (which writes it into web.config).

I hope this helps.
