Upgrade 2.12.1 Agents stopped sending inventory

Question

Hello

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 : 

'ocsinventory-agent
--nolocal --ssl=0 --ca=/etc/pki/ca-trust/source/anchors/cert.pem --info
--server=http://dummy-url.com/ocsinventory'

We got this in the log : 

ocsinventory-agent.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

The results of a tcpdump command shows an "Encrypted Alert" error

192.168.5.67  = remote host

192.168.5.228 = 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
