Hi, I've been having an odd error when connecting new agent nodes. On a fresh Ubuntu 24.04 VM, I run the following command:

sudo curl -sfL <https://get.k3s.io> | sudo sh -s - agent --node-ip=fd98:8e41:1daa:ba::c5d --token TOKEN --server https://[fd98:8e41:1daa:ba::8d7]:6443

The IPs are definitely correct and the node does register successfully. However, traffic does not successfully reach the pods - with an Nginx default deployment, I get 504 Gateway Timeout responses for anything sent to the agent node, whereas any traffic going to the pods on my server node responds with the default Nginx page, as expected. Looking in my logs, there's a repeated error of 'invalid argument', although I can't find where that argument is! I've attached a copy of the logs, but what it seems to conclude with is

failed to add v6 vxlanRoute (fd98:8e41:1daa:ea02::/64 -> fd98:8e41:1daa:ea02::): All attempts fail:

Is this a bug or am I the error? Thanks!
