In my last two articles, I’ve showed you how to deploy Microsoft Dynamics NAV 2016 on Azure using Azure SQL Server. Now, if you already finished it any you want to use NAV Web Client, you have to install Web Server components on VM you configured as service tier and create Endpoint for WebClient on this VM, opening port 8080. Now you have to login with different username (for example, Admin username you already used on your VM). Now, you have to type the following URL: http://<AzureVM_Name>.cloudapp.net:8080/DynamicsNAV90/WebClient/
If you have problem with connecion and get the error message, this is probably because port 8080 is not opened. If you want to open this port, you have to open Remote Desktop Connection to your VM and run the following: Control Panel > Windows Firewall > Advanced Settings > Inbound Rules.
If you can find “Microsoft Dynamics NAV 2016 Web Client” as rule, you need to add 8080 as Local Port. But if you cannot find it, create a new rule (using the command in the right pane) and add this name and local port.
