Hi, so have a new server running on centOS 7. Mac clients work fine. But windows clients is having problems.

From the event viewer on a windows client

Event ID 20

Service encounter error < Failed to load/parse last inventory state>

Hi,

Error 400 means you have a ocs agent version greater than ocs server version. What are ocs server and agent version ?

As I see the content of error.log file php headers and client library aren't be at the same software level. Update. Plus set date.timezone in php.ini and restart apache. Then launch a new inventory.
