Hi Team,

Flow:- On-Prem---->GCP(Interconnect) ---->External-LB---->Palo Alto---->Internal-LB---->GCVE.

This is the flow/architecture we have in our environment. I have observed one thing when we enable both VM instance then LB showing in unhealthy state.

I have attached the screenshot. Please let me know how to solve this issue.

Hello,

We have the following network flow in our environment: On-Prem → GCP (Interconnect) → External Load Balancer → Palo Alto → Internal Load Balancer → GCVE. I have noticed that when both VM instances are enabled, the load balancer shows an unhealthy state. I have attached a screenshot for reference. Please review the issue and advise on how to resolve it. You can also refer to my provided link and the attached screenshot for more details. myccpay com
