Dockerfile start-dev vs start

I’m using the Dockerfile on this page as a base: Running Keycloak in a container - Keycloak running version 20.0.2

When running start-dev with no options, it’s running fine, however when running just the “start” command, the site fails to load and a js error appears:

Uncaught (in promise) {error: 'Timeout when waiting for 3rd party check iframe message.'}

Any ideas as to how I can combat that? I’m deploying the Docker image via AWS CDK

I have the same issue running keycloak-20.0.2 in a virtual machine I when try log in the console

Most likely this is an issue with proper hostname configuration.
And/or proper proxy settings.
