Can't connect to Mongodb Replica Set when adding replicaSet as parameter - mongodb

Question

I've recently followed the aws quick start cloudfront deployment for a 3 node mongo replica set.
I've set up an NLB so they are accessible from my local network and am trying to connect via mongo shell.
Trying
mongo "mongodb://<username:<password>#<url1>,<url2>,<url3>"
connects me to the database but doesn't always connect to primary so must be the incorrect way of connecting
Trying
mongo "mongodb://<username:<password>#<url1>,<url2>,<url3>/?replicaSet=s0"
I get the error
Error: Could not find host matching read preference { mode: "nearest" } for set s0
The /etc/mongo.conf is
net:
port: 27017
bindIpAll: true
systemLog:
destination: file
logAppend: true
path: /log/mongod.log
storage:
dbPath: /data
journal:
enabled: true
security:
authorization: enabled
keyFile: /mongo_auth/mongodb.key
processManagement:
fork: true
pidFilePath: /var/run/mongodb/mongod.pid
replication:
replSetName: s0
And the rs.conf() is
{

"version" : 1,
"protocolVersion" : NumberLong(1),
"writeConcernMajorityJournalDefault" : true,
"members" : [

}
],

"getLastErrorModes" : {
},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("myid")
}
}

Any advice on what I might be doing wrong would be appreciated
