I have a GKE cluster with Ingress Nginx Controller attached to a Internal Load Balancer in GCP. The TLS termination happens on Ingress side.
I have 2 networks: A and B. Machines from network A are able to connect to my portal.company.com with TLS, but machines from network B got timeout. If I remove TLS from my portal.company.com both networks are able to connect.
Looking to ingress nginx logs I have SSL handshake problems on network B, see:

I believe the issue might be with certificate or firewall settings.
