Symptoms

A TLS 1.3 handshake failure occurs when using openssl's AES-GCM cipher in FIPS mode.

Impact

Handshake failure for TLS 1.3

Conditions

FIPS mode and attempting TLS 1.3 with cipher AES-GCM

Workaround

Disable FIPS mode, or alternately use non AES-GCM cipher for TLS 1.3.

Fix Information

TLS 1.3 AES-GCM in FIPS mode now works correctly.
