Can't connect to GCP VM website with external IP

Question

Trying to connect to my django website (from the browser) that's stored on the GCP virtual machine. Everything works fine if I'm accessing it internally using internal IP or localhost.

However, I can't access website with external IP. No logs in django that would say someone trying to access if I'm trying with external IP.

I have http, https traffic enabled on instance.

Firewall rule to allow port 80:

Here is Test-Net results.

Searched the web for answers but nothing looks wrong in my settings.. Any ideas would be appreciated.

UPDATE:

1. Do not create or change egress rules unless you know exactly what they do. They are not necessary for ingress rules (VPC Firewalls automatically allow return traffic):

I've changed all firewall rules back how they were so now only port 80 is allowed.

2. You have an ingress rule for the target http-server. Is that target flag set on the VM instance?

3. What is the output from sudo lsof -i -P -n | grep LISTEN? Your Django server must be listening on 0.0.0.0.0 instead of localhost.

I have 0.0.0.0 with port 80 at django terminal. I use windows 2016 server so don't know the powershell function that would display what you asked for. Here is netstat listening ports for django.
