Hi,
I've just switched the network cards on some of my VPS from Vlan100Mbps to a Vlan 1Gbps.
(I removed the 100Mbps card and added the new one, reboot the server)
But when I try to ping another VPS (that still use the 100mbps netword card), I get an error "a destination host unreachable"
The VPS runs on Ubuntu 20.04 and use Netplan.
Any help (or Guide)?
