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

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??

1. Question - Have all routers the same firmware?
2. Question - Are all routers directly connected to the internet without other devices between them? All with fixed IPs?

@noci I'm agreed of what you are saying but everything depends on the model of the router he has.

Technically speaking, I'm guessing he's knows all that and I'm just giving him a general idea of what could it be.
And where to go.

Thanks for the advice people, it's been a couple of days but I've solved my issue.
I don't really understand why it's working now, but rebuilding my config (exactly the same) fixed this issue.

Routers

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
