Hi,  
I have configured following resources in Azure Portal:
 
  • Virtual Network (Named as VN_1)
  • 2016 Server Virtual machine (SVR2016)
  • Win10 Client Virtual machine (WIN10)
 
Here my intention is to configure terminal server license in SVR2016 so that multiple users (more than 2) can connect and use this machine, so I have configured the required Terminal server license in this machine.
 
The local network IP address of the SVR2016 is 10.0.X.X and the public IP address is 52.172.Y.Y.  Now I can able to successfully connect this server machine from WIN10 client machine with more than 2 users at the same time using local network IP address, but I can't able to connect with more than 2 users from the same machine using Public IP.
 
Overall the Terminal Server license is working fine in local network but it is not working through public IP address.

hello!

Along with the article mention by Clay Huang, I would also check the network security polices on the public interface and if there is a tier base policy not allowing more than the configure amount of sessions open on the public interface.

Once the update windows server 2016, that issue was fixed. Now I can connect more number of users via public IP address.
