mongodb-kafka-base-mongod fails when mongo have ssl enabled

Question

I followed the documentation (Quick start) docker compose file and everything went fine. Tried to add ssl to mongo instance using this tutorial: generate-mongo-ssl.md

then went to ssl part and followed the steps

I updated my docker-compose to have certificates as volumes

      ]
    restart: "no"

networks:
  localnet:
    attachable: true

mongo1-setup was failing so I took this mongosh --tls --host mongo1 --tlsCertificateKeyFile /etc/ssl/mongodb.pem --tlsCAFile /etc/ssl/mongodb-ca.crt config-replica.js and ran it inside mongodb instance, it succeeded,

Now when I go inside mongodb instance and run

curl -X POST \
     -H "Content-Type: application/json" \
     --data '
     {"name": "mongo-source",
      "config": {
         "connector.class":"com.mongodb.kafka.connect.MongoSourceConnector",
         "connection.uri":"mongodb://mongo1:27017/?replicaSet=rs0&ssl=true",
         "database":"quickstart",
         "collection":"sampleData",
         "pipeline":"[{\"$match\": {\"operationType\": \"insert\"}}, {$addFields : {\"fullDocument.travel\":\"MongoDB Kafka Connector\"}}]"
         }
     }
     ' \
     http://connect:8083/connectors -w "\n"

I get no logs from mongodb instance and from connector side I get 2023-06-27 19:50:44 Caused by: java.net.ConnectException: Connection refused (Connection refused)

How can I complete the tutorial while both the connector and the mongo instance have ssl enabled. I tried to ping mongo1 from connector, it went fine. Also tried mongosh --tls --host localhost --tlsCertificateKeyFile /etc/ssl/mongodb.pem --tlsCAFile mongodb-ca.crt went fine

if any details is missing please let me know

UPDATE: I solved it by updating mongod.conf bindIp to mongo1
