I'm setting up my Kubernetes Cluster using Azure AKS and I deployed NGINX Ingress following this guide: https://docs.microsoft.com/en-us/azure/aks/ingress-internal-ip

Now the guide works great for the demo applications it demonstrates on but when I tried deploying one of my own apps the page only showed the html parts and for the js, css and png parts I got the following errors in the Console:

When I deploy the application without NGINX Ingress on my K8S cluster it works perfectly but for some reason when I deploy it through NGINX I get these errors.

I also tried deploying another app, pgAdmin, and for that I only receive an error 503 when I try to approach its' page.

I tried several workarounds I found on the web but nothing seemed to fix it.
