Not able to get site to site VPN up

Hi,

I am trying to a get a site to site VPN link up and I get this error message :

Me@EdgeRouterPro8:~$ sudo swanctl --log
12[IKE] sending retransmit 3 of request message ID 0, seq 1
12[NET] sending packet: from 111.111.111.111[500] to 222.222.222.222[500] (156 bytes)
04[NET] error writing to socket: Invalid argument

What would you suggest I look at? I'm a bit lost, I have reviewed my configs multiple times... This is what show vpn ipsec sa is giving me:

Me@EdgeRouterPro8:/$ show vpn ipsec sa
peer-222.222.222.222-tunnel-1: #1, CONNECTING, IKEv1, 12c0fc157b5e816f:0000000000000000
  local  '%any' @ 111.111.111.111

And Show vpn debug gives:

Me@EdgeRouterPro8:~$ show vpn debug
