No response from VM Scale Set

Question

I created a VM ScaleSet from a custom image where Docker is pre-installed. For testing, I just run on all available VMs this command: sudo docker container run -d -p 80:80 seqvence/static-site (just showing a simple static site on port 80). However, I first created a healthProbe (just checking for tcp:80). Then I created a loadbalancing rule for port:80 -> backend port:80. And of course my LoadBalancer has a backend pool containing my VMs of my ScaleSet.

But when I now navigate to myvmss.westeurope.cloudapp.azure.com I get ERR_CONNECTION_TIMED_OUT

What am I missing?

Hours of checking LoadBalancing configuration and the app inside my VMs.... and then you are absolutely right - it was the NSG -.- thank you! — Munchkin, Aug 03 '17 at 08:51

Port 80 was blocked by Network security Group.
