OSPF neighbor not coming up "Drop packet, OSPF shut down on interface"

OSPF neighbor can't come up on a DMVPN spoke.

It all started with this message. Tun0 interface has always been up and connectivity has been verified.

*Apr 17 15:26:13.312: %OSPF-5-ADJCHG: Process 302, Nbr100.10.0.1 on Tunnel0 from FULL to DOWN, Neighbor Down: Interface down or detached

debug ip ospf packet

I am unable to find anything about "Drop packet, OSPF shut down on interface". Known bug?

Hi

Could you please share the config of both routers? Are you redistributing the source and destination into OSPF as well?
