Hello. On a site-to-site VPN that was working fine yesterday...
On our end there is a ASA5505. On the other end is a Fortinet appliance. As I said - the tunnel has been fine for months.
The other side moved their datacenter to a new location - same IPs, etc... basically jsut turning things off and back on but our tunnel isn't coming back up. (It shows in the ASDM monitor as connected but no traffic and this error in the logs:
IKEv2 Negotiation aborted due to ERROR: The peer's KE payload contained the wrong DH group
Any idea what may be going on? Thanks.
