Description
It would seem that there is an upstream bug with wireguard icmp and path discovery (?) : https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=ee576c47db60
All my issues were resolved by setting the MSS field to 1420 (which enables an mss clamp of 1380) on my assigned wireguard interfaces.

This seems to no longer be a requirement, as WireGuard by design should be able to pass larger MTUs within the tunnel.
Not seeing this on the latest kmod code
