  1. This is a community managed forum if you need critical support, opening a support ticket is the best way to get help. https://support.mongodb.com/

  2. It looks like these hosts isn’t available, I would check that the MongoDB process is running successfully on the host, the host is reachable. If the nodes and processes are up I would verify they can communicate over port 27017

  1. What is the topology of the database? A replica set?

Yes, 1 primary, 2 secondary.
