Console fails with SSL configured "unable to verify the first certificate"

[LeeDr]

Kibana version: 5.4.0-SNAPSHOT

Elasticsearch version: 5.4.0-SNAPSHOT

Server OS version: Ubuntu 14.04

Browser version: Chrome

Browser OS version: Windows 10

Original install method (e.g. download page, yum, from source, etc.): .deb packages

Description of the problem including expected versus actual behavior:
The integration-test repo was recently changed to configure SSL for all products for 5.x and master branches. The Dev Tools > Console now fails with the message;
"Bad Gateway",\n "message": "unable to verify the first certificate"

Steps to reproduce:

1. Follow docs to configure SSL between browser client and Kibana and between Kibana and Elasticsearch. I think the configuration is OK since everything else in Kibana works.
2. Try the default request in Console
3. <"statusCode": 502,\n "error": "Bad Gateway",\n "message": "unable to verify the first certificate"\n}'

Errors in browser console (if relevant):

Adding this to kibana.yml makes console work;

console.proxyConfig:
    - ssl.verify: false
