I'm stumped and also quite surprised I didn't find a solution to this using Google/SuperUser.
I have NordVPN installed, and I'm using this page to configure that connection to a specific IP address go through my regular home connection and not through the VPN. It's a straightforward process of using "route add" in the terminal (as administrator).
I tried this on two different computers under the same network with the same NordVPN account. After I add the route to example.com (as in their instructions), and try to ping it, I get this result:
C:\WINDOWS\system32>ping 93.184.216.34

Deleting the route makes the ping go through again:
C:\WINDOWS\system32>route delete 93.184.216.34 10.0.0.138
OK!
C:\WINDOWS\system32>ping 93.184.216.34

10.0.0.138 is my router, it's the first line under "route print". This happens on two different laptops (one with Windows 10 and one with Windows 7). Anyone has any idea?
Thanks!

Edit 2:
This is the second laptop (Windows 7) so the interface is now 10.0.0.15, but it's the same deal. route print with VPN connected:
