I got this problem while mounting with loop

I get the error “Failed to configure loop device.”
I’m trying to mount a CentOS iso to do a Network system boot, but it is giving me this problem while configuring the HTTP Server, any fix on this?

The command I’m trying is this one mount -o loop CentOS-7-x86_64-DVD-1611.iso /mnt

Try to upgrade and reboot:

sudo dnf upgrade
sudo reboot

Load the module manually if the issue persists:

sudo modprobe loop

Thanks!, just tried the solution you gave me, but the issue persists after the solutions, Any other fix for this?

Specify full path to the image file.

Thanks, I needed to upgrade and also specify the full path <3
