I'm seeing the following error in the Kibana logs:

Request error, retrying\nHEAD [https://xxxxxx:9200/](https://xxxxxx:9200/) =\> Hostname/IP doesn't match certificate's altnames: "Host: [xxxxx.eu-west-2.elb.amazonaws.com](http://xxxxx.eu-west-2.elb.amazonaws.com). is not in the cert's altnames: DNS:xxxxxx""

This is despite providing a CA with [xpack.monitoring.elasticsearch.ssl.ca](http://xpack.monitoring.elasticsearch.ssl.ca).

Kibana itself shows a page with Status: RED and lists this error message:

plugin:monitoring@5.6.2 No Living connections

How can I disable hostname verification for the monitoring url?

Hi @lgee,

by default even certificates from trusted CAs must contain the correct hostname. If you want to explicitly disable the hostname check, try setting `xpack.monitoring.elasticsearch.ssl.verificationMode` to `"certificate"` instead of `"full"`.
