Is the wireguard module loaded? I doubt it.

You are running a *very* old kernel, and I suspect the version of 
kmod-wireguard you are running does not support that kernel. Why are you 
running a kernel that is two years out of date and full of unpatched 
security holes? Updating your system is probably the first step to 
fixing your issue.
