'pymongo MongoClient connection failed due to pymongo.errors.ServerSelectionTimeoutError: mongo1:27017: [Errno -3] Temporary failure in name resolution
I have installed 3 node mongodb with replicaset.
Docker images are started to bind all ip address.
command: mongod --replSet engline-rs --journal --bind_ip_all
I am able to connect the database using
mongodb://admin:password@localhost:27017/?authSource=admin
in robo3T or mongodb compass. But with the same uri my python code is not able to connect to the server.
Got below error:
pymongo.errors.ServerSelectionTimeoutError:
mongo1:27017: [Errno -3] Temporary failure in name resolution,
mongo3:27017: [Errno -3] Temporary failure in name resolution,
mongo2:27017: [Errno -3] Temporary failure in name resolution,

Any help is appreciated.
