Secure communication protocol negotiation error

Hello,

We have updated the version of Data Protector from version 10.60 to version 10.91, it ended without errors, even a backup of the IDB has already been made, but when executing the backups there are communication problems, we have this error:

[Critical] From: BDA-NET@srv001 "G: [BACKUP]" Time: 21/7/2022 14:43:36
Cannot connect to Media Agent on system cm001, port 121949 (Secure communication protocol negotiation error when trying to establish a connection.
Check the validity of certificates and their configuration.
) => aborting.

We have run omnicc -secure_comm -configure_peer commands on both sides (CM and client) without success.

Please, where could be the error?

Regards

Rafael
