Can’t access the cluster with robomongo. It says failed to connect to “HOSTNAME OF THE PRIMARY” via SSL tunnel, disabling SSL doesn’t help, the message is the same without the SLL part. Mongo CLI client works fine but I don’t hate myself enough to write aggregation pipelines in the CLI. Authentication db is admin, sha 1 is used. The default DB is set to aggregations.
It’s a connection string problem. Share the connection string and a screenshot.
By the way, MongoDB Compass has a nice interface for writing Aggregation pipelines.
