Hi Paulo,

Please try below settings if that helps

In file sqlnet.ora in the <DB_HOME>/network/admin location add the following parameter: SQLNET.ALLOWED_LOGON_VERSION_SERVER=8, it defines the minimum version of authentication protocol permitted to access the database. Prior to version 12c the default setting for SQLNET.ALLOWED_LOGON_VERSION (the equivalent parameter prior to 12c) was 8. In 12c the default is now 11.

Check note 1718415 and 1714490.
