ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Once cert is uploaded and the appliance reboots. No further ability to access the appliance over port 443 is possible at this point
it shows the following error at url:
XX.XX.XX.XX uses an unsupported protocol.
PAM 4.x
The issue was caused PAM's automated process that reviews the certificate and tries to validate if the certificate if is RSA or ECDSA. PAM will then assign the appropriate ciphers for that specific certificate. In this case PAM misinterpreted the certificate type and assigned the wrong ciphers.
This is resolved in PAM 4.1.8 and 4.2.1 versions specifically, but the appliance must be rolled back if this was already rebooted, or a Broadcom Support engineer must login using ssh to manually set the database with the correct ciphers.
