mongodb remote authentication failure Mongod v4

[Mohd Sufian]

I have recently installed mongodb on one of our windows 2016 server with below configuration and running mongod as

enter code here

mongod --config C:\mongo_db\config\mongo_db_configuration.conf --auth

--config file
net:
    # MongoDB server listening port
    #bindIp: 0.0.0.0,192.168.43.250
    port: 27017
    bindIpAll: true
storage:
    # Data store directory
    dbPath: "C:\\mongo_db\\db"
    mmapv1:
        # Reduce data files size and journal files size
        smallFiles: true
systemLog:
    # Write logs to log file
    destination: file
    path: "C:\\mongo_db\\logs\\mongodb.log"
security:
  authorization: enabled

We have created a root user in admin database

    enter code here
MongoDB Enterprise > db.runCommand({connectionStatus:1})
{
        "authInfo" : {
                "authenticatedUsers" : [
                        {
                                "user" : "root",
                                "db" : "admin"
                        }
                ],
                "authenticatedUserRoles" : [
                        {
                                "role" : "dbAdminAnyDatabase",
                                "db" : "admin"
                        },
                        {
                                "role" : "root",
                                "db" : "admin"
                        }
                ]
        },
        "ok" : 1
}

I am able to connect to the mongod instance locally (mongo --port 27017 -u "root" -p "12345" --authenticationDatabase admin) but getting error while connecting remotely.the server firewall is disabled.

"C:\Mongodb>mongo.exe 192.168.0.171:27017/admin -u root -p 12345

Hi,

The error login failed implies that the username/password combination for the authentication database (admin) is incorrect. The presence of this error means that there should be no network issues.

Could you confirm that you’re connecting to the correct server at 192.168.0.171? I noticed that you commented out the IP address 192.168.43.250 in your config file. Do you have multiple MongoDB servers running in your network environment?

Best regards,
Kevin

I have the same problem with him:local authentication can be successful but remote authentication failed,my mongo version is 4.2.2 , the mongodb has run 5 months and the maxsize datafile of the collection is 180GB(only one file is 180G),all the other factors is not changed,I guess it is related to the huge file size but I am not sure.please help me many thanks.
