DX VLAN tagging QinQ

Hello,

We have a hosted connection on VLAN 125 and AWS Direct Connect Partner/Service provider provided the VLAN 3166.( probably qnq tagging)

We have configured the vLAN 125 on our on prem router with dot1q encapsulation. However I can not ping the amazon peer ip sourcing from our peer ip which in turn fails our layer 2 test. How can I resolve this issue ?

Any suggestions or guidance is highly appreciated .

Thanks
