Nginx Kubernetes Ingress does not serve .ttf or .woff files
Some CDN services has a cors configuration that need to be configured.In my case i added a cors authorized domain on my digitalocean space.This solved on firefox and chrome.
Verify wich type of installation you have made and verify you have the nginx-config configmap. See docs
If you don't have, create one and set this in the data area:
data: gzip_types: application/x-font-ttf application/font-woffAnd if you need more gzip_type you could add too. Here are the default values.
If the problem is the gzip config like you say this will solve your problem.
