Could you share the output of the below debugs:

di de reset
di de flow filter clear

di de flow filter x.x.x.x

di de flow show ip en

di de fl trace start 1000

x.x.x.x is the loopback IP

Once the above commands are run, please initiate the VPN, and once the error is seen, please stop the debug using:
