Nginx reverse proxy domain not reachable

Dear people,

I have been using docker on linux ubuntu 18.04. I have been following the tutorial on, then I couldn’t reach the blog part.
I tried adding another domain with a container, gitlab. That also worked fine and with a specific port given, I could also reach it. So how is it possible that can’t reach the blog?

I hope someone can help me with this problem.

With kind regards,
