All working and service down automatically. that means no configuration changed ?

 

what was the change ? links upgraded, hardware upgraded ?

Check basic check as mentioned below documents :

https://community.cisco.com/t5/security-documents/dmvpn-on-spoke-troubleshooting-order-and-component/ta-p/3143396

 

Most of the errors you can see on both the devices, post the logs.
