GrayLog on Debian

I have a Debian VM running, wireguard VPN, and PiHole. I want to run a GrayLog server for my UDM SE for logs. For some reason, I can’t get it to work. I try to go to and the page does not load. Am I doing something wrong? I followed the instructions.

Is the elastic service running? Is the Graylog service running? What’s in the /var/log/graylog-serverserver.log? DId you use the docker version?
