same for me

The likely culprit was this line of code just above the reported line:

                $interfaces = glob('/sys/class/net/*');

Likely at the time this was hitting up against an open_basedir() restriction (or similar).

However that was in NC23. We no longer get the list of network interfaces that way. We now use PHP's own net_get_interfaces() and that line of code is long gone.

Let's close this Issue out.

Please open a new issue if anything similar appears in a currently supported version of NC. It'll be for a different reason. :)
