Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo' when I use ifdown or ifup

When using ifdown or ifup for the lookback interface in CentOS 7:
[root@localhost etc]# ifup lo
I have got the error below:
Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'
Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'
Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'
Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'
However if I use the ifconfig command, it shows the command(ifdown or ifup) works with success.
As I tested, the use of the ifconfig lo up/down does not show any signs of errors.
What is happening?
EDIT
I checked the ifcfg-lo file, it shows the info below:
[root@localhost etc]# ls -la /etc/sysconfig/network-scripts/ifcfg-lo
-rw-r--r--. 1 root root 254 Jun 26 20:07 /etc/sysconfig/network-scripts/ifcfg-lo
centos ifconfig

Does chmod a+rx /etc/sysconfig/network-scripts/ifcfg-lo correct the situation? (probably not, I suspect it must be something with selinux...)

@RuiFRibeiro it still reports the error. and in the front, I tells it even reports the mentioned error but the command works.

First of all stop Using ifconfig command anymore with Centos 7 version and later versions because it doesnt give you full information about your network card parameters (For example if you assigened 2 IP addresses to your Card)
instead use ipa command or ip addr show command.
Second This problem is currently being tracked as a bug by Red Hat.
To Fix this problem: Add NM_CONTROLLED=no to /etc/sysconfig/network-scripts/ifcfg-lo.
Root Cause: ifcfg-rh plugin in NetworkManager does not support loopback interface type and logs a message about it in system log.
