Google Cloud routing

Hi everyone,
I have two hosts in GCP connected to the same MongoDB Atlas. On the VPN servers, I attach both hosts and set the replication count to 2. I’m using routes without NAT.
The client connects to one of the hosts randomly. If I create static routes to both hosts with the same priority, the traffic only goes to one of them.

How should I configure routing in GCP to be able to reach the VPN client?
