I had this exact issue today and here's what I did: For my issue, the SHC had a static captain. So I followed the Splunk docs to try and get them to become a RAFT distributed consensus voting for the captain. When I ran the commands the SHC cluster broke. After looking around for a while in the conf files I change two things on the non-captain servers. In server.conf, the mgmt_uri was pointing to the existing captain. That has to be its own self per instructions in server.conf and delete the captain_url stanza. After I deleted those I restarted Splunk and ran the command pointed to the captain who was still the cluster splunk add shcluster-member -current_member_uri <URI>:<management_port> I repeated that for the other hosts until the captain was left When I went to the captain I made sure that "mode = member" and deleted the captain_url stanza. When I restarted that host was no longer the captain and another had picked it up. Hope this helps
