Multiple IPs are not getting bind in mongodb conf file
had the same issue and the thing is everywhere it's written that you have to bind them like this

bindIp : 127.0.0.1,192.168.0.50

but that doesn't work.

The MongoDB version 3.2.x have the following configuration and its working for me.

    bindIp : [127.0.0.1,192.168.0.50]

    example :

# network interfaces
net:
      port: 27017
      bindIp : [127.0.0.1,10.12.2.1,10.12.65.1]
