I have a 220.127.116.11 Dragon EMS server and sensors. One sensor (HIDS running on Linux) shows the Event Channel down in the reporting dashboard, and the management client shows it unable to communicate. The HIDS sensor keeps logging "[net-cfg-client (25650)]: Could not connect: Connection timed out." What should I look at to fix this issue? I've got other sensors working just fine, this is my odd box.
