IPSec ike VPN wont connect after 24h

Hi,

I have a strange issue where I create a peer and test the tunnel and everything’s working.
I disconnect the device (Digi modem) and replug it 24h later and the VPN wont come up with an error :
Phase 1 negotiation failed due to time up.

I have a routerOS 6.30 running on VMware with fault Tolerence


Here’s my peer config :

3    ;;; 10.69.0.5
      ;;; Unsafe configuration, suggestion to use certificates
      address=0.0.0.0/0 local-address=0.0.0.0 passive=no port=500 auth-method=pre-shared-key secret="MY-SECRET-KEY" generate-policy=port-strict policy-template-group=Digi exchange-mode=aggressive
      send-initial-contact=no nat-traversal=no proposal-check=obey hash-algorithm=sha1 enc-algorithm=aes-256 dh-group=modp1024 lifetime=1d lifebytes=0 dpd-interval=1h dpd-maximum-failures=5

Here’s my Policy

2 T   group=Digi src-address=0.0.0.0/0 dst-address=0.0.0.0/0 protocol=all proposal=Digi template=yes

here’s my proposal

name="Digi" auth-algorithms=sha1 enc-algorithms=aes-256-cbc lifetime=1d pfs-group=modp1024

My modem are connecting using a cellular modem and have dynamic IP.

Anyone have an idea where he didnt seem to rekey?

Regards
