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:
Decryption disabled:
Decryption enabled:

So basically it seems that the only solution for this is limit the decryption my excluding ECDHE from Key Exchange Algorithms or enabling Strip ALPN. I definitely hope that PA will consider putting this change from 10.x.x also back to 9.x.x.
Can anybody confirm exclusion of ECDHE or ALPN stripping had solve this issue for them?
