I'm running a .NET Docker application on an Azure VM, and while the container works perfectly when I access it via `localhost` from inside the VM, I'm unable to reach it using the public IP address. I've confirmed that the container ports are mapped correctly, but it still doesn't seem to be accessible from outside the VM. Any ideas on what might be going wrong?

Are you binding your Docker app to `localhost`? If that's the case, it will only be accessible from the machine itself. Change it to `0.0.0.0`, which will allow it to listen on all interfaces. You can use `netstat -a` to see what IP addresses and ports are currently listening on your VM.
Have you checked your Network Security Group (NSG) settings? You might need to allow inbound traffic for the specific ports that your Docker container is using. Also, make sure that you're forwarding the public IP traffic to the VM's local IP.
Good point! I didn't realize that. I'll check the binding settings in my Docker configuration.
