MongoDB Setup

[willzzam]

I'm trying to use this tool with MongoDB and I've followed the steps in the readme but its timing out the connection.

ERROR 2021-09-28 10:28:31,866 [[MuleRuntime].uber.10: [metrics-accelerator].loader-mongodb-loader-flow.BLOCKING @15332cd4] [processor: loader-mongodb-loader-flow/processors/0; event: a9df6a60-2070-11ec-a5da-ca09a8ae6bc2] org.mule.runtime.core.internal.exception.OnErrorPropagateHandler: Exception(s) were found for route(s):
Route 0: Caught exception in Exception Strategy: Timed out after 30000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=mongodbd3.local:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketReadException: Prematurely reached end of stream}}]

is there something that I'm missing in the MongoDB setup like setting up a Index to receive the metrics or is it Mongo somehow blocking the metrics from connecting?
Also is it because my login information is not encrypted?
