I see this is kind of an old post, but we are running across the same situation. But rather, we need to change from using an IP address to using hostnames, so that we can change subnets. First, I go into the server.conf file and change the mgmt_uri from: mgmt_uri = https://10.16.6.53:8089 to: mgmt_uri = https://servername.domainname.com:8089 Then restart splunk then run: splunk show shcluster-status I get this: Encountered some errors while trying to obtain shcluster status. This node is not part of any cluster configuration, please re-run the command from an active cluster member. Also see "splunk add shcluster-member" to add this member to an existing cluster or see "splunk bootstrap shcluster-captain" to bootstrap a new cluster with this member. If it go through these steps of (set static captain, remove member, rename mgmt_uri, enable cluster using hostnames, add member), the cluster will come back up, but then I get "error resolving hostname" on the SH Deployer
