Hello!
No, there were no errors, but I have an update - mine is working also!
So it looks as if Setienne’s last line “I had to wait almost 20 minutes to be able to access the screen.” is relevant to me. It didn’t say anywhere in the instructions that it took time for the system to go live. It took around 15-20 minutes for the site to actually start working after running the docker-compose up -d command.
Thank you both for your responses!
