Hello,
connection to the OCS server fails with the actual version of OCS.
current version of Win64 agent 2.6.0.1 (same issue with agent 2.6.0.0)
current version of OCS server 2.7
The log file of the windows agent contains the following message:
Starting OCS Inventory NG Agent on Sunday, April 5, 2020 06:00:32.
AGENT => Running OCS Inventory NG Agent Version 2.6.0.1
AGENT => Using OCS Inventory NG FrameWork Version 2.6.0.1

Also in the apache log on the server you could the eror code 400
Some clients have an older version of the Windows agent (2.1.1.). With the older agent the communication with the server works.
