IPsec Tunnel working, but not for one of the P2 on site 3

[ggorman]

One of our IPsec tunnels is not connecting correctly.
Is working correctly from another site to site.

Each site uses pfSense, CE, or Plus editions.

Currently, the configuration of the works on site 2 to site 1

Private network: 10.27.0.0/24

Connecting through IPsec tunnel to Main site on private network
10.24.0.0/22
10.24.8.0/24
10.24.28.0/22
10.48.0.0/18

Our 3rd site (P2 not working)

Private network 10.28.0.0/24
Connection through IPsec tunnel to Main site on private network.
10.24.0.0/22
10.24.8.0/24
10.24.28.0/22

Same information for the P2 setup on both; however, on the 3rd site, it will not connect to the additional private network.

Configuration of P2 for both sites is the following.

Networks:
Local Network: LAN subnet
Nat: None
Remote network: Network: 10.48.0.0/18

Phase 2 Proposal: This is set up like other P2 connections.
And is pointing to the correct P1

Have a Static route setup as well on 2nd and 3rd site
10.48.8.0/24 to LANGW on lan interface.

I've gone through the guide for doing IPSec setup many times and setup is correct on both ends. However, I feel like I'm over looking something very simple.

Thanks for any tips.
