Problem with VPN Site-to-site on Cisco ASA

Hello everyone,

I have a problem with one of ours VPN Site-to-site tunnel on Cisco ASA 5515-X, can you take a look on this log:

I already work on this log, and i can see QM FSM ERROR, it seems to refer to crypto ACL but there are both correct, it's the same ACL

I always get Received non-routine Notify message: Invalid hash info (23), can anyone tell me what is the problem of this???

Finally, i get Received encrypted packet with no matching SA, dropping but i get the exact SA on both site. I don't get it...Can you just tell me where i have to search on my config? Thank you very much for your support!

Here's the log:

QM FSM error (P2 struct &0x00007fff2ac41340, mess id 0xce302ad7)!

Hi Edward,

Hi Edward,

From the existing logs it's not clear what is the issue.

FSM error is an generic error. Also we see "Duplicate Phase 2 packet detected.  Retransmitting last packet" this looks the previous packet is not received on the Remote end and it send the Qm1 again.

To better understand the issue take the condition debug for that particular site.

debug crypto condition peer x.x.x.x

debug crypto ikev1 255

debug crypto ipsec 255

And the captures on the outside interface. Add entire debug ouputs + captuers.

Hello, swj and thank you for

Hello, swj and thank you for your answer!!

With the debug crypto condition peer x.x.x.x, there's nothing happen..nothing to show you...

How do you debug outside interface?

I think i have a same crypto map for different tunnel, could be the reason of the problem?

Thank you

On the debug crypto ikev1 255

i can see this log:
