By using Visual Studio, you can publish your website directly to an Azure Virtual Machine. After selecting the VM in the Publish wizard, you may come across this error message: “Could not reach the Web Deploy endpoint on the specified virtual machine“
Solution for “Could not reach the Web Deploy endpoint” error
Turn off Windows Firewall to see if the issue occurs again. You can turn it back on after testing. If it works after turning it off, it means there is an issue with the inbound rule.
In order for Web Deploy to access a virtual machine, that machine should be listening the port 8172. Run the command below in the VM to see if it is listening to this port:
netstat -ano | findstr :8172
Then, make sure that IIS Management Service is installed and running:
Finally, go to IIS Manager and open “Management Service”. Check if it is enabled for remote connections.

I wanted to mention a similar Web Deploy related issue. While trying to deploy your application from Visual Studio to IIS website, you may run into the error below.
Could not connect to the remote computer. On the remote computer, make sure that Web Deploy is installed and that the required process (“Web Management Service”) is started. Learn more at https://docs.microsoft.com/en-us/iis/publish/troubleshooting-web-deploy/web-deploy-error-codes#error_destination_not_reachable. The remote server returned an error: (404) Not Found.
One of the most common causes of this issue is the missing management component for the Web Deploy installation. In order to solve it, uninstall and install Web Deploy back by selecting all components in the wizard.
