Docker windows: hitting DNS resolution timeout/cancelled after 50 networks

I am using windows host. And spinning 2 hyper-v containers in each service. each service is creating its own network. I am able to scale upto 50 services … each service has correct 2 containers in its own network.

issue starts from instance 51. when my container_1 resolves the DNS of another container_2 (in same network/service) … DNS resolution is timing out.

question: does anyone know where is this 50 limit? any workarounds to unblock here. is it any windows firewall or hyper-v or docker or network limit?

Thank you in advance !
