Keycloak Docker On Azure Web App - Web UI 404 Not Found

I am facing a weird issue with the keycloak docker images (i tried both the jboss/keycloak as well as quay.io/keycloak/keycloak and found the behavior to be the same).

Here is my (rather simple) Dockerfile :

FROM jboss/keycloak:latest

ARG ADMIN_USERNAME=myadminuserid

ARG ADMIN_PASSWORD=myadminpassword

ARG REALM_NAME=abstracta

ENV PROXY_ADDRESS_FORWARDING=true

RUN /opt/jboss/keycloak/bin/add-user-keycloak.sh -u $ADMIN_USERNAME -p $ADMIN_PASSWORD

The very first time, I deployed this into Azure Web App, it worked and I was able to login to my admin console and setup the realms and everything.

But then, after a couple of restarts, it started showing this weird behavior. When I accessed the admin console, it started showing 404 not found errors for various components (in the browser developer tools).

Refused to apply style from 'https://mydomain.azurewebsites.net/auth/resources/95t8j/common/keycloak/node_modules/patternfly/dist/css/patternfly.css' because its MIME type ('') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

There are more errors, everything points me towards the fact that the web application was not deployed correctly.

From a UI perspective, it turns up a blank page or sometimes with broken image placeholders etc.

This would be a deal breaker for us. Please look into this with utmost priority.
