Decryption failed

L0 Member

Hi guys , 

PA820 . OS Version 10.2.9-h1

 

I am try using the decryption function to see more application information
I generated the CA certificate from PA and imported it locally.

From the decryption log, I saw many errors with various URLs.
Can anyone help explain how to eliminate this?

 

error eq 'Received fatal alert CertificateUnknown from client. CA Issuer URL (truncated):http://cacerts.digicert.com/DigiCertGlobalG2TLSRSASHA2562020CA1'
URL: http://aia.entrust.net/l1k-chain256.cer'

Hello @HY_Cheng 

 

It seems like you're dealing with a classic incomplete chain issue.

This often occurs with SSL/TLS certificates when the server doesn't provide the full certificate chain, excluding the root certificate.

Cheers,
Cosmin
