This post is regarding some troubleshooting procedures for strange certificates issue during configuration PKI based IPSec vpn between Juniper SRX Firewalls.
Symptoms:Â
The VPN Tunnel could not be built although all procedures have been followed, generated RSA key pair, generated CSR on both SRX firewalls, submitted CSR to SSL certification provider, received certificates for both devices, received CA certificates, and imported all certificates into devices.
Debugging IKE did not give too much information. But during verify certificates, I found these strange information:

Both Devices CA certificate chain did not pass the verify. On SRX1, G4 and G5 CA certificate did not pass verify, and on SRX2, only G5 failed, although I imported same certificates on both devices.
Troubleshooting:
Let have a look at the files we got from Symantec Verisign:
1. ssl_certificate.crt is firewall's  certificate which is signed by Verisign CA certificate.
2. IntermediateCA.crt is CA certificate chain file which includes two certificates.

After saved each part of certificate chain into a file, I checked the certificate property for each certificate.
From the certificate properties, we can tell "Symantec Class 3 Secure Server CA - G4" is signed by "VeriSign Class 3 Public Primary Certification Authority - G5" and "VeriSign Class 3 Public Primary Certification Authority - G5" is signed by "Class 3 Public Primary Certification Authority"
From below output, local certificate SRX1 is signed by "Symantec Class 3 Secure Server CA - G4"

I checked the Symantec page "Licensing and Use of Root Certificates", and found there is another G5 certificate.
Downloaded it and checked the property from Windows:
This new G5 certificate will expire on 2036 and has same Issued to and Issued by, which means it is Root CA certificate. The old G5 will expire on 2021 and have different Issued to and Issued by , which means it is signed by another root CA certificate. Now I am kind of understand Symantec Certificate Chain by drawing following diagram:
Solutions:
Now it is quite clear, with those originate certificates sent from Symantec, I only have G5(2021) and G4 for CA certificate chain. I am missing one root certificate "Verisign Class 3 Public Primary CA".
I can either import another new ca certificate to complete this chain, or replace G5(2021) with the new G5(2036). I choose replace option.
All steps are listed in the following:
