How to determine UnknownSpnHint correct value in web.config in NAV 2016 Web Client pointing to a load balancer

Hi everyone,
I would like to ask you these questions because we have the following problem. We have an installation with two nav boxes that run the nav server instances and in front of them there is an application load balancer and also two web server boxes exist for the web client. Both web.configs are mapped to the ip of the application load balancer(obviously the two nav server machines have the same nav server instances,are using the same ports,configuration in order the load balancer to transmit requests to both nav machines.

We have seen that UnknownSPNhint has different navserver values between the two web servers,the one has application load balancer ip and the other one the fully qualified domain name of one nav server box.
Microsoft says in MSDN for web.config that for the web client this value isn't automatically updated but we have seen that web.config is being changed from time to time for this setting. The default NoSPN value always remains the same,but the NavServer is changing in the net.tcp://NavServer:Port/ServerInstance/Service part of the setting.
Also if NoSPN is the value of the setting,does it make any difference and the ServicePrincipalNameRequired = False, will the different NavServer affect the web client?
Thanks in advance and any help is much appreciated
