Ike failure usually means phase 1 is down, not phase 2. Can you run vpn tu and check what it shows when you filter for that specific tunnel?

Or try below options.

Andy

 

vpn tu list ike
vpn tu list ipsec
vpn tu list peer_ike ip-addr
vpn tu list peer_ipsec ip-addr
vpn tu list tunnels
vpn tu tlist
vpn tu mstats
vpn tu del ipsec all
vpn tu del ipsec ip-addr
vpn tu del ipsec ip-addr username
vpn tu del ipsec ip-addr from ip-addr to ip-addr
vpn tu del all
vpn tu del ip-addr
vpn tu del ip-addr username
vpn tu del ip-addr from ip-addr to ip-addr
vpn tu conn

Hmmm unclear error. Maybe VPN debug could give more info.

In the mean time maybe you can check the basics. This will be as I assume certificate based tunnel.

So maybe check if the CRL check is working:

Also check if the VPN certificates are still valid:

This is not a Gaia embedded gateway right?

Hello,
what LSM Gateways do you use and what Version are they running on?

Is there a Log Entry from an LSM GW?
