The peer 188.8.131.52 is responding but the VPN tunnel in not established. IPSec policies of this router are not matching with the IPSec policies of the peer device.
If the IPSec policy parameters of the peer device is known then go to 'Configure->VPN->VPN Components->IPSec->IPSec Policies', select this IPSec policy, click on 'Edit' and ensure that policy parameters are correct. 2) Generate the mirror configuration from 'Configure->VPN->Site to site VPN->Edit Site to Site VPN' and match it with the peer device's IPSec policy.
