edit: My answer only addresses the problem of a failing mongodb service after system reboot. If your service is failing after a service restart on a running system you have a different problem.

The problem is that at the time of mongodb service start the IP address is not yet available.

To fix this you can set up a systmed service overwrite rule:

sudo mkdir -p /etc/systemd/system/mongodb.service.d
sudo vim /etc/systemd/system/mongodb.service.d/ip_bind.conf

Add the following lines

[Unit]                                                                           
After=network-online.target

This will overwrite the default rule After=network.target. On my system (Ubuntu 20.04) the default mongodb service configuration is located in /usr/lib/systemd/system/mongodb.service.

First of all, as bindIp parameter accepts string, the syntax of your value looks fine.

You can get the complete output of your service using journalctl command, you can use the following command,

journalctl -xe -u mongod.service

The logs there, will show you the complete error logs.

You can also check the logs of mongod process which is configured in your configuration file under systemLog.path.

You should be using the only IP Addresses at which the mongod will be listening, so you can check your IP addresses once again.

Below is my configuration file,

net:
   bindIp: 127.0.0.1,192.168.100.101
   port: 27018

It works just fine.
