Upgrade 2.12.1 Agents stopped sending inventory


We are currently upgrading our OCS Inventory Server from 2.11.1 to 2.12.1, with the OCS Agent Unix 2.10.0. 

After upgrading, we noticed that the agent stopped sending inventories to the server, so we tried to troubleshoot by checking the logs and the configuration file : 

After executing this command on the remote host to connect to the server : 

--nolocal --ssl=0 --ca=/etc/pki/ca-trust/source/anchors/cert.pem --info

We got this in the log : 


[Mon Feb  5 14:01:01 2024][info] Going to sleep for 96 second(s)

[Mon Feb  5 14:02:45 2024][error] Cannot establish communication : 500 Internal Server Error

[lun. 05 févr. 2024 14:02:45 UTC] End of cron job (/sbin:/bin:/usr/sbin:/usr/bin)

[lun. 05 févr. 2024 15:01:01 UTC] Running ocsinventory-agent --wait 100 --nolocal

--ssl=0 --ca=/etc/pki/ca-trust/source/anchors/cert.pem --info




# OCS Inventory "Unix Unified Agent" Configuration File


# options used by cron job overides this (see /etc/sysconfig/ocsinventory-agent)


# Server URL, unconmment if needed

server = https://dummy-url.com/ocsinventory

#local = /var/lib/ocsinventory-agent

# Administrative TAG (optional, must be filed before first inventory)

# tag = your_tag

# How to log, can be File,Stderr,Syslog

logger = Stderr

logfile = /var/log/ocsinventory-agent/ocsinventory-agent.log

  # User allowed to connect to database

  PerlSetEnv OCS_DB_USER ocs

  # Password for user

  PerlSetVar OCS_DB_PWD ocspsswd

  # SSL Configuration

  # 0 to disable the SSL support for MySQL/MariaDB

  # 1 to enable the SSL support for MySQL/MariaDB




define("DB_NAME", "db_ocs");












The results of a tcpdump command shows an "Encrypted Alert" error  = remote host = ocs server 

Note that the Ocs agents used to send inventories properly to Ocs Server before we upgraded, and the content of the configuration files attached are the exact same in 2.11.1 and 2.12.1 version.

We are also getting a "500 Internal Server" that we didn't used to get even though we are still using the same certificate.

Is there anything missing for the upgrade to be successfull ? 

Do we need to upgrade some files in order to make a successfull upgrade ?

Thank you, 

Best Regards
