Local application connects Mongo through ssh tunnel is not working

I have a ssh tunnel that linked to a remote mongo server. I tried to use this local tunnel with mongo-java-driver in Play server. It throws time-out error. But I can use mongo command line to connect to this tunnel and operate this database without issues.

This is the tunnel command:

ssh -f -L 127.0.0.1:27018:$remote_ip:$remote_mongo_port $remote_user\@$remote_host -N

This is the mongo.url I used:

mongodb.default.uri="mongodb://acct:[email protected]:27018/mydb"

However, it throws this error while trying to connect.

Caused by: com.mongodb.MongoTimeoutException: Timed out while waiting for a server that matches {serverSelectors=[ReadPreferenceServerSelector{readPreference=primaryPreferred}, LatencyMinimizingServerSelector{acceptableLatencyDifference=15 ms}]} after 9999 ms

Try using -R instead of -L, -L makes a local port forward to a remote port which can be read on the server which you're connecting to. -R on the other hand forwards a remote port to a local port, which is what I'm guessing you're trying to do.

ssh -f -R 127.0.0.1:27018:$remote_ip:$remote_mongo_port $remote_user\@$remote_host -N
