@Karthick.Subbiah,

Make sure that you aren't decrypting the traffic via a decryption policy. 

Thank you for your response.

 

We do have a decrytption policy in place and we cant remove it. kindly advice the next course of action.

@Karthick.Subbiah

Try to disable the checkbox at "validate update server identity" and mark the root cert that you use of decryption as trusted root certificate. Not sure if this really works because the actual solution was already posted by @BPry. For this step you don't need to disable TLS decryption comoletely, just configure an exception for your firewall mgmt IP to wildfire.paloaltonetworks.com.

@Karthick.Subbiah,

Yup as @vsys_remo pointed out and exactly what I meant; you don't disable decryption all together, you simply create an exception so that this traffic isn't decrypted. I believe that the other soultion that @vsys_remo presented will still fail, but I could be wrong.
