The internet stopped working all of a sudden. Like I couldn't ping yahoo.com for example. See attached screen shots of `ip addr` and `/etc/network/interfaces`.
Anyone any ideas?

Running Proxmox 6.3

As you can see in the brackets, the interface is up, therefore it is highly likely that the problem lies outside of Proxmox.
Are you able to ping to IP addresses rather than domain names? Is your DNS server running? Is a firewall blocking the access?
