Could be a subnet issue as your computer is set to 10.0.0.1 and the node is at 10.100.60.200.
Try changing the nodes IP to something in the same Class C, such as: 10.0.0.200
Also, check that your Subnet Mask is set properly(e.g. 255.255.255.x)
dot2 and grandMA2 work great in the 10.x.x.x range with both ArtNet, sACN & MA Net. I've been running this IP range for years without any issue using four class C's (10.0.0.1-10.0.3.255) and a subnet mask of 255.255.252.0 I gave myself four class C's so I'd have plenty of room to grow, and separate client equipment that I maintain for them from my own equip(but will be able to communicate with each other).
