So I installed an application on the Ubuntu Azure Linux VM and it's running on 127.0.0.1 (localhost). I want it to be accessible to the public through the VM's public IP address. I did a ping check to verify the installation and it works just fine on localhost. It's sending packets. I want to access it through the VM's public IP address. I tried adding an inbound rule that allowed all traffic from any port and protocol, but this too didn't work.
