I am looking to this #535 (comment)

servers: 3 (hetzner)
agents: 4 (oracle and strato)
All nodes are configured with a wireguard mesh on 10.8.0.0/24 on wg0
The behavior you are describing indicates that UDP traffic between cluster members is being dropped. You might see if you need to reduce the MTU in order to fit the encapsulated VXLAN traffic through the wireguard tunnel.
You might also try using the built-in wireguard/tailscale support, to avoid double-encapsulating your traffic:

I'm going to convert this to a discussion, as it appears to be a configuration issue, not a defect in k3s.
