Any idea?

Hi, I discussed this issue in a recent live coding stream (https://youtu.be/5EpsA2raV0k) so others with the same issue can be pointed in the right direction.

In short, the solution is to check that nothing else is assigned to port 80. This isn't just limited to containers. If you had a LAMP stack running in the VPS you would get the same issue.

I recommend using Docker machine instead of your own VPS as this is a clean Docker environment.
I have some tutorials on Docker Machine here: https://youtu.be/RA4vAJSMtEc

As I cannot replicate this issue I need to close it but I hope this helps
