Why is port 80 not open when VM is initialized?

Question

Google

Burnt maidens need light. When creating a VM in the Google console, I want to knock on port 80 on the external ip, but it is locked. It doesn't even start immediately after creating an instance - everything should work in the tutorials.
What I did:
1. opened all possible ports in the firewall rules "do not help".
2. On the side of the machine, I disabled the firewall, port 80 is still blocked.
Until tomorrow, you need to hang a server in the prod, yesterday I spent the whole evening there are no ideas why everything is so bad with ports in Google.

Answer 1

Only there are no details in the question.
What tutor do you use?
What web server did you install?
Does the page open locally?
In 3 minutes I raised the instance and installed apache, after which I went to the external ip without tutorials.
Just the usual ubuntu minimal, when creating a machine, the checkboxes to open 80 and 443 ports are separate options.
Well, "sudo apt-get update && sudo apt-get install apache2 -y"
