This would be complicated to debug in own network with 11 hopes, with Internet
and no visibility to other side it may not be possible solve.

What you could try is add secondary addresses on your 'working' VLAN, like 10
addresses in row. And source ping from each of them. If you observe packet
loss on some address in 'working' then we can pretty safely assume it's
ECMP/802.1AX issue somewhere in path.
