Anyone with Site to Site VPN just suddenly disconnected?

My Flex 500's will not reconnect. I've deleted configurations. Started over. Zyxel engineer looked at settings, deleted settings.

Nothing!! Any ideas?

    Hi @PCbytheSA,

    Since the information is short, I need more information to help you.

    Could you share:

    1. Your site-to-site VPN topology,
    2. The VPN event logs on the two sites/firewalls.
    3. The configuration of your two firewalls.

    With those information, I can help to check this issue.

    P.S. If this issue occurred on many sites/firewalls, please share the information from all of them.
