Symptoms:
Worked on IPSec VPN Certificate for whole morning to try to import a certificate, finally gave up to ask support from Verisign. I did this many times and had detailed documentation recorded for steps. But this time, situation is different.
My previous post clearly shows all steps I have to follow:
Unfortunately, this time the process stuck at the step 6 with error “% Failed to parse or verify imported certificate“
m-dmz(config)#crypto pki import VerisignCA1 certificate
Enter the base 64 encoded certificate.
End with a blank line or the word “quit” on a line by itself

I even tried following method which I googled from Internet. I created multiple Trustpoint just in case I missed a root certificate since I were only using one ‘RSA Secondary SSL Intermediate CA Certificate’ in Symantec Article AR2108, which I tested it before and was working.
“I ended up using the following order based on the digicert tutorial to complete the install. The trick is to have an empty first trust point, which has the first intermediate cert, and a second trust point using the “chain-validation continue [FirstTrustpointName]” with the second intermediate certificate and the ssl cert.
crypto ca trustpoint VPN-Trustpoint

rsakeypair vpn-sslkey

Solution:
After I gave up my troubleshooting and gave a Verisign support a call, the mystery is resolved with a clear and simple cause. Symantec is using a new Intermediate CA G4 for new certificate with Signature hash algorithm: SHA-256 shows below. Verisign did not update their Article for the link to this new Intermediate CA yet. But you will get it when download your certificate from your account.
You will get a zip file includes following files:
ssl_certificate.crt is your ssl certificate. IntermediateCA.crt is the new G4 certificate. Previous one in the article AR2108 is G3 and G5. I was able to use G3 only to get certificate imported and validated in my previous post
I copied new Intermediate G4 certificate at below for future reference, although feel disappointed for Verisign not able to update their website and not email right thing to customer. Hopefully it is only me to have this pain.

By the way, if you have imported wrong Intermediate certificate, you do not have to delete trustpoint as shown on the cisco route
v-dmz(config)#crypto pki authenticate VerisignCA1
% Please delete your existing CA certificate first.
% You must use ‘no crypto pki trustpoint <trustpoint-name>’ to delete the CA certificate.
I found it is working by just delete “crypto pki certificate chain VerisignCA1” with command
v-dmz(config)#no crypto pki certificate chain VerisignCA1
Then you could re-import your intermediate certificate without remove your trustpoint. If you completely remove the trustpoint with Cisco’s suggestion ‘You must use ‘no crypto pki trustpoint <trustpoint-name>’ to delete the CA certificate.’, you will have to end it up with re-create your trustpoint , your CSR and re-submit your CSR. That will take a long time to get your certificate from your CA.
