We creating an updated deployment of our Linux devices based on the latest Redhat Enterprise Linux 9.3 

ZENworks agent 23.4 deployed using repo. The agent finally works fine, but registration process takes 45 minutes to op to an hour. 

Anyone seen this? 

Windows devices register fine. This takes only a couple of minutes.

Already tried creating a new reg key. There are no bundles or policies connected to the folder where de devices are created.
