I think I found the problem, when setting up proxmox, proxmox defaults to enp27s0 which is not connected to a network. It does not detect enp16s0 which is the one connected to the network.
So my suspicion was correct. However I didn't expect for it to not recognise the Mellanox card installed.
You can install a cable for both interfaces. You just need to specify the IP address of the 10Gig interface when doing file transfers otherwise if you use hostnames Windows will likely pull a stupid and use the slower NIC.
