ERPNext Setup Wizard hang

I have just installed ERPNext in Docker according to the instructions.
Since Traefik is already running on my own, I took this container out and adjusted the settings.

I can call it up and log in as admin and then this wizard comes.

If I select the domains (retail, distribution, etc.) and want to continue clicking, it doesn’t go any further and I get stuck, so to speak.

Who can help me here. The JS doesn’t seem to be working.

Setup wizard on develop branch has error
