L2Gw connectivity not working from 16-March-2017

Hi,

For the HWVTEP configuration, we do the l2gateway and l2gateway connection creation for verification which used to create the VXLAN ports.

From 16-March-2017, it is not getting generated and all HWVTEP L2gateway connection verification are failing.

Can someone please help to point out if there are any changes to the auto tunnel or anything which got delivered yesterday which could have caused this?
