Error node not found when setup replica set in mongodb - mongodb

Question

I'm having extreme frustration trying to setup a MongoDB replica set from scratch.
I have 2 machine run debian os and installed mongodb. When i try use rs.add() to add member to replica set then i appear error although i still connect to mongodb by
mongo --host 13.212.31.212:27017
Here is the error messages
rs0:PRIMARY> rs.add("13.212.31.212:27017")
{
"operationTime" : Timestamp(1597144435, 1),
"ok" : 0,
"errmsg" : "Quorum check failed because not enough voting nodes responded; required 2 but only the following 1 voting nodes responded: 192.168.0.59:27017; the following nodes did not respond affirmatively: 13.212.31.212:27017 failed with Received heartbeat from member with the same member ID as ourself: 0",

}
}
}
Here is the mongod conf
# Where and how to store data.

what i am doing wrong ?

Answer 1

This is the descriptive error message:
the following 1 voting nodes responded: 192.168.0.59:27017; the following nodes did not respond affirmatively: 13.212.31.212:27017 failed with Received heartbeat from member with the same member ID as ourself: 0"
That is telling you that 192.168.0.59:27017 and 13.212.31.212:27017 are the same node, and you can't add the same node twice.
