NR error in istio gateway with NLB-IP mode in aws load balancer

[parshva-shah-dsw]

We have configured a nlb-ip mode load balancer for istio-gateway. by following the below documentation :-
https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.1/guide/service/nlb_ip_mode/
https://www.eksworkshop.com/docs/fundamentals/exposing/loadbalancer/ip-mode/#:~:text=The%20AWS%20Load%20Balancer%20Controller%20also%20supports%20creating,through%20the%20worker%20nodes%20in%20the%20Kubernetes%20cluster.

after making this changes in the load balancer mode we are getting NR error in the gateway while executing the requests the same gateway and virtual service configuration is being used which works in instance mode load balancer.

can we have any help here with any documentation on configuration with gateway

@parshva-shah-dsw What do you mean by NR error? Could you be more specific?
Did you see the NLB targets to be healthy with this config?
