We have identified that your virtual machine(s), have firewall or application issues blocking port(s):"80".

This issue is caused by a virtual machine (VM) application and/or firewall misconfiguration that is blocking network traffic to the application. By default, VM applications have to be configured to listen on particular TCP/UDP ports to receive requests from the networking layer. A firewall rule must also be configured to allow this traffic through.

We have already opened "80" port as well in VM nsg but still facing this.

Hi @x2mannashr4pa2 ,

there are some more things you could check:

Depending in the OS of the VM you can check the VM OS Firewall settings

Please check if the web service is running and listening on port 80

NSGs could be associated with the VM (you already checked) and with Azure vNets/Subnets as well. If there are more than 1 NSG is involved you should check this as well.

Are you running a firewall in Azure (3rd party or Azure Firewall)?
