Chrome version: 71.0.3578.98
OS version: 71.0.3578.98 (ChromeOS), current Linux (Rodete)
Case#: 17913836

Description:
Same HTTPS website with self-signed certificate shows different error on Linux-based systems (Linux and ChromeOS) and others.
On Windows/MacOS it shows NET::ERR_CERT_AUTHORITY_INVALID, which allows to proceed or add to trusted
On Linux/ChromeOS it shows NET::ERR_CERT_INVALID, which doesn't give an option to proceed and adding it to trusted won't help.
I tried to bisect on Linux, but found the same behavior up to version 55, so I suspect it's not browser version related, but OpenSSL/BoringSSL issue


Steps to reproduce: 
1. Go to https://35.247.17.70/
2. Check error message

Current Behavior / Reproduction: 
NET::ERR_CERT_INVALID

Expected Behavior: 
NET::ERR_CERT_AUTHORITY_INVALID

Certificate file with key I used as example (on https://35.247.17.70/) -

Req file used to generate -

What I noticed is that adding Extended Key Usage triggered this error, however we had another report with certificate not having this field, so it might not be the only trigger.
