Our SDP is installed on a debian Linux install.  We have recently started upgrading the agent version on the assets from a combination of either 1.17 or 1.19 to version 1.22.  To perform the upgrade on the systems, I went into assets and workstations, workstations with older agent versions. and would select machines and then go to actions and then upgrade.

some of my systems would install the upgraded agent correctly, others I had to connect to the system' registry and add the information for the agent port, server port, protocol, and server name into the registry HKLM/software/ZOHO Corp/manageengine asset explorer/ agent (I know this varies depending upon x86 and x64 OS)

On some of the units that are not updating the SDP I have restarted the system, or just restarted the service and the system still shows up in SDP and agent not installed. I have even tried uninstalling the agent and removing the directories and registry entries and they will still not talk to the server. The log files are being generated, the xml files are updated, but the server is still not showing any of the info on the server

does anyone have any ideas of what else to try?

below is the aeagent log:
