HI we are running elasticsearch on a windows server machine. I have recently changed the ip address of the server, and now I'm getting lots of messages in the log file containing lines such as org.elasticsearch.transport.ConnectTransportException: [Gaia][inet[old.old.old.old:9300]] connect\_timeout[30s] Somehow elastic search is using the old ip address not the new one but I've been unable to find out where this coming from ? (I've replaced the old ip address in the log file) Is there a setting somewhere for the ip address I need to change ? Regards ---

What is `network.host` set to in your config? ---
