See https://api.mongodb.com/python/current/examples/high_availability.html#mongos-load-balancing > Warning > Do not connect PyMongo to a pool of mongos instances through a load balancer. A single socket connection must always be routed to the same mongos instance for proper cursor support.

Rely on multi-node connection string for MongoDB-HA cluster instead of using loadbalancer single host which is not desired for prod deployment.
