Hi Experts

I have never configured Site to Site VPN for Juniper srx240h2 and I have a customer that want me to setup Site to site VPN. Since I'm not familiar CLI for this Juniper SRX, I followed from this link (only for Juniper as for both Firewall are same Juniper SRX) .
I did not set "Step 3 - Additional Steps required (for Cisco ASA)" as I assume it is only required if one site is ASA.

After done, when I check in - Interface - port - S0.1 I can see it is showing UP.
And in Monitor tab - IPsecVPN- Phase 1 , also it is showing as UP.

But I cannot ping from one site to another site internal IP.
I can see policy to allow from Local subnet to remote subnet, remote subnet to local subnet is automatically added.

Software versions are as follows:
1. JUNOS Software Release [12.1X44-D15.5]
2. UNOS Software Release [12.1X44-D10.4]
Any suggestion why it cannot connect each other ? What else I can check to troubleshoot ?
