I have installed kibana following the elastic guide and configured it to point to my two elastic node via elasticsearch.hosts: ["[https://xx.xx.xx.xx:9200](https://xx.xx.xx.xx:9200)","[https://xx.xx.xx.xx:9200](https://xx.xx.xx.xx:9200)"]. The only other settings i've changed are the server.host variable to the IP of the host and the elastic username and password to the kibana\_system user. However when starting i get this error, but unsure how to fix it: ` Feb 16 10:48:14 kibana[29468]: DeprecationWarning: Setting the TLS ServerName to an IP address is not permitted by RFC 6066.

> [@rashmi](#): > > As a potential workaround this could work: > `NODE_OPTIONS="--no-warnings" yarn start --run-examples` That example is for running Kibana from source. It's close, but I don't think it will work without an export (read more below). @Gosborne I reformatted the logs that you provided: ```auto Feb 16 10:48:14 kibana[29468]: DeprecationWarning: Setting the TLS ServerName to an IP address is not permitted by RFC 6066.

Feb 16 10:48:17 systemd[1]: Failed to start Kibana. ``` This looks fairly straightforward. Starting in Node 12+ (which we upgraded Kibana to use in the Kibana 7.11 release), Node will emit this warning when you try to establish a TLS connection using an IP address. You should use a hostname or a fully-qualified domain name (FQDN) instead. But this isn't something you'll have to worry about in production for a long time. As to why this is causing a start failure: are you running Kibana from source? If you are doing so and running it in dev mode ( **not recommended for production** ), it is [configured throw an error when encountering a Node deprecation warning](https://github.com/elastic/kibana/pull/51431). I recommend using the default distribution of Kibana which you can download [here](https://www.elastic.co/downloads/kibana), but if you need to get this working in dev mode for some reason, you can use this command to run Kibana from source: ```auto export NODE_OPTIONS="--no-warnings" && yarn start ``` The `export` directive is needed to make this environment variable available to the Node process when running it with `yarn start`. ---
