kein IPsec VPN nach Upgrade auf SFOS 20.0.1 MR-1-Build342

Hello,

all our Site-to-Site-VPN don't work again after upgrading from SFOS 20.0.0 GA-Build222 to SFOS 20.0.1 MR-1-Build342.

In the log we find: 

(unnamed) - Couldn't parse IKE message from ..

Also all outgoing remote IPSec don't work again after upgrading:

Child SA (Security Association) konnte nicht hergestellt werden.

Can anyone help?

Thanks

Uwe
