Hi,
after downgrade from 6.34.4 to 6.32.4 the ipsec vpn is not connecting :
failed to get valid proposal
failed to pre-process ph1 packet (side :1, status 1)
phase 1 negotiation failed
Upgrading or downgrading again to main versions does not solve the problem.
I’ve created again the peer, deleted the group, enable and disable the peer.
Thanks.
