SSL Decryption: ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY

L1 Bithead

Hi paloalto community,

 

we're currently still testing ssl decryption and discovered a new error, which I can't google to find a solution.

 

If we're visiting the following site, we get an "ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY" error. Site: https://www.1erforum.de/

 

See attached our configuration and ssl information without decryption enabled.

 

Firmware and Specs:

PA 850 - FW 9.0.5

 

Settings:

Same issue for us also ....

This is what we also did.  So far, just a handful of sites.  As somebody else pointed out, this article is helpful https://tools.ietf.org/html/rfc7540
