After update to my xg firewall to v20 ipsec is become unstable. Randomly disconnection. openvpn client work without issue only ipsec have problem

Some info: this setup worked for 2 year without a problem (another bug on v19 but fixed). Sophos firewall on main branch and 2 remote location both with fritzbox 7530

strongswan.log show ike timeout and successive reconnection. Both line, both random. 5min, 10min, 60min ther no a real pattern.

Already try increase key time as the Troubleshoot but no change.

the sophos side have 2 wan. Already try switch one vpn to the other wan. no remarkable change

remote can ping external ip of the main without losing packet.

Thanks for any help
