Description
For testing purpose I'm tring with NGINX web server:
1.
docker run -d --net isolated_nw -p 80:80 --name nginx nginx
docker exec -ti nginx bash
2.
root@formica-VirtualBox:/home/lprunella# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED
STATUS PORTS NAMES
60ec8fc5fda8 nginx "nginx -g 'daemon off" 5 minutes
ago Up 5 minutes 130.206.119.28:80->80/tcp, 443/tcp
docker-host-2/nginx
3.
root@formica-VirtualBox:/home/lprunella# docker --config ~/.docker network
inspect isolated_nw

But when from browser I attempt to connect to the web server at
130.206.119.28:80 I have no response. I have also checked with 8000:80.
Thank you

The user contacted me directly. The problem is fixed.
The problem below is that you are using an absolute host port mapping " -p 80:80". It should be "-p 80". Docker will auto assign a port that is mapped to the container's port.
You can fetch the host port mapping with "nginx_uri=$(docker port nginx 80)". We don't allow absolute port mapping because there mean tenants would be competing with each other for ports.
