MongoDB port listening in loopback ip address when restarting the system

Hello Team,

I am facing the timeout exception for the following steps,

1. Restart the system
2. Communicate mongoDB from one of the windows service throws timeout exceptions.

While analysis I found that the mongoDB port listening the loopback ipaddress 127.0.0.1 when restarting the system. At this point I am getting the timeout exception.

After restarting the system, I tried restarting the MongoDB service also. It started listening with ipv4 Address and port. And communication works properly.

My question here is, why the MongoDB is taking loopback ipAddress while restarting the system.

Any helping hands??

MongoDB version - 4.0.10

C# dll version

MongoDB.Driver- 2.10.1.0
MongoDB.Driver.Core- 2.10.1.0
MongoDB.Bson -2.10.1.0
MongoDB.Libmongocrypt - 1.0.0.0

Hi Jack,
Thanks for response.
Yes I tried bindIpAll parameter and it solved the issue.

But my doubt here is, why MongoDB service is taking loopback ipAddress while restarting PC? is it possible to clarify this?

Hi Jack,
So everytime when the PC is restarted will MongoDB start using loopback address?

Hi Jack,

Coming back to my first question.

I have created the service initially with the following parameter

“C:\Program Files\MongoDB\Server\4.0\bin\mongod.exe” -f “C:\Program Files\MongoDB\Server\mongodb_config.yml” --bind_ip=hostname --port=9876 --serviceName “MongoDB” --serviceDisplayName “MongoDB” --serviceDescription “MongoDB Server” “–dbpath=C:\data” “–logpath=C:\data\log.txt” --service

Here I have used only --bindip paramater which has the value of fully qualified hostname.

after service created, it started listening with ipv4 static address(ex: 123.87.98.187) with the port 9876.

Now, I am restarting the PC, my expectation is that the port 9876 should listen in the same ipv4 static address(ex: 123.87.98.187). But it is listening with loopback ipAddress 127.0.0.1. Due to this communication is not happening and timeout exception is occuring.

Why this difference happening in MongoDB component? or what should I change to make it works properly?

I have removed the default service. And then I created the new service with this command line and set it as autostart by default.

I have tried bindip with network interface address as well. But after restarting the System, MongoDB service is not started automatically. Service is set to auto start only. So Manual restart is required.

It is not solved my issue.

Can you tell us, when MongoDB service will take loopback ipaddress or which kind of environment makes the MongoDB port to listen with loopback ipaddress.
