Proposal errors on IPSEC IKEv1 VPN between Flex 500 and USG 40

I'm trying to setup a S2S VPN between 2 sites, one using a Flex 500 and the other is a USG 40.

I've tried creating the objects manually and with the wizard but both times I get "No proposal chosen" errors in the log.

I have double checked the phase 1 parameters and they all match.

Is there a trick to this that I'm missing?

    Are both devices showing "no proposal chosen"?
    Is one of the devices behind NAT?

    Is it possible to provide remote access to your devices? you may contact me via private message, thanks.
