I’ve already switched from standalone to replica set doing the steps in this wiki:
https://docs.mongodb.com/manual/tutorial/convert-standalone-to-replica-set/
I’m able to connect to the replica set (tried it with Compass), and see the data but the migration tool is always failing with this message:
Live Migration encountered an error: could not initialize source connection: could not connect to server: server selection error: server selection timeout current topology: Type: ReplicaSetNoPrimary Servers: Addr: localhost:27017, Type: Unknown, State: Connected, Average RTT: 0, Last error: connection(localhost:27017[-9]) connection is closed
I’ve whitelisted all four subnets, I even tried to open it to all IP’s and it still failed
