Configure an external load balancer to distribute traffic to the NSX Managers in a manager cluster.
While configuring the VIDM configuration on the NSX Manager getting below error :-
VMware NSX
The issue occurred because the hostname entered in the VDIM configuration was being validated against the NSX Manager directly, instead of the Load Balancer VIP. By enabling the External Load Balancer option, NSX correctly recognizes that the traffic should go through the Load Balancer VIP, which makes the hostname validation pass and resolves the error
This issue is resolved after enabling the check box for External Load Balancer Integration.
