Hi, I have followed documentation - to setup kibana development environment for creating custom plugin. However the server crashes due to following error - [oracle@obdcnode7 kibana] yarn start yarn run v1.10.1 sh ./bin/kibana --dev watching for changes (1740 files) log [11:25:40.913] [info][server] starting basepath proxy server at [http://172.18.27.86:5601/ywz](http://172.18.27.86:5601/ywz) server log [11:25:47.641] [info][status][plugin:kibana@6.4.4] Status changed from uninitialized to green - Ready server log [11:25:47.672] [info][status][plugin:elasticsearch@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:47.675] [info][status][plugin:xpack\_main@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:47.680] [info][status][plugin:searchprofiler@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:47.683] [info][status][plugin:ml@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:47.735] [info][status][plugin:tilemap@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:47.738] [info][status][plugin:watcher@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:47.753] [info][status][plugin:license\_management@6.4.4] Status changed from uninitialized to green - Ready server log [11:25:47.756] [info][status][plugin:index\_management@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:49.038] [info][status][plugin:timelion@6.4.4] Status changed from uninitialized to green - Ready server log [11:25:49.040] [info][status][plugin:graph@6.4.4] Status changed from uninitialized to yellow - Waiting for Elasticsearch server log [11:25:49.050] [info][status][plugin:monitoring@6.4.4] Status changed from uninitialized to green - Ready server log [11:25:49.058] [warning][security] Generating a random key for xpack.security.encryptionKey.

Looks like an error from the TLS certificate. But for development you can just disable SSL and security so that you don't have to create a new certificate. ---

I am able to start the server using yarn start -oss flag. Is there any other option to disable ssl? Also how can we resolve this issue? Thanks. ---

By default there shouldn't be any certificate setting, but you can use `yarn start --ssl` in order to use Kibana's self-signed certificate and this should remove any errors. Otherwise, just check if you have modifications done in the `config/kibana.dev.yml` file. ---

Hi, I tried starting kibana using -ssl flag but server crashed with error - server error [08:57:52.128] [fatal] Error: getaddrinfo ENOTFOUND [github.com](http://github.com) [github.com:443](http://github.com:443) at errnoException (dns.js:50:10) at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26) FATAL { Error: getaddrinfo ENOTFOUND [github.com](http://github.com) [github.com:443](http://github.com:443) I got this same error when yarn tried installing geckodriver.Also my installation doesn't contain any kibana.dev.yml file but contains only kibana.yml file which have not being modified with any ssl related setting. Thanks. ---
