Why is universal forwarder phonehome not interpreted by deployment server?
I have been monitoring a few Windows hosts with Splunk Universal Forwarder installed. I have setup a deployment server on a linux host to manage configurations on these hosts. Recently, I have moved one of these windows hosts to another subnet. Then I found the deployment server cannot receive any phonehome from this host. Then I checked splunkd.log and splunkd_access.log, found no log with the windows host's hostname/IP observed. However, on the Linux host I run tcpdump and found the Windows is actually sending traffic to the deployment server's port 8089. So the regular phonehome message is actually sent to the deployment server but cannot "recognize" it as phonehome message. Do you have any idea what could possibly go wrong? I have actually re-installed the universal forwarder on that host but the issue is not solved. Splunk version is v8.1
