IPSEC: 3 Site-to-Site VPN's - Only 2 are working, keep getting IKE link timeout: state linking

Last Modified: 2018-01-02
I'm fairly new to VPN services so I don't really know what's happening and why.

I am trying to connect 3 remote sites to HQ by using site-to-site VPN and have managed to get 2 working.
The 3th one won't come online and I cant really figure out why, I have used the exact same config on all 3 routers (Vigor2925) for Outbound connections (except for local subnet ofcourse) and the same inboud settings for HQ router (also Vigor2925).

When I check the syslog on the remote site, it gives the following error:
[IPSEC][L2L][1:Wessem-Out][@WAN IP] IKE link timeout: state linking

On HQ I keep getting this one:
Responding to Main Mode from <WAN IP REMOTE SITE>
Accept Phase1 prorosals : ENCR OAKLEY_DES_CBC, HASH OAKLEY_MD5

Can someone maybe explain what im doing wrong??
