Atlassian Cloud throwing SSL error 'site uses a weak security configuration' in Chrome on El Capitan
Platform Notice: Cloud Only - This article only applies to Atlassian products on the cloud platform.
Accessing your Atlassian Cloud instance in Chrome shows 'https' crossed out. Clicking for more information shows the error:
This site uses a weak security configuration (SHA-1 signatures), so your connection may not be private.
- OS X El Capitan (earlier than beta 5)
- Google Chrome (latest version)
The SSL certificate is valid, it appears to be a problem with Google Chrome and El Capitan: https://code.google.com/p/chromium/issues/detail?id=499506
Update OS X El Capitan to Beta 5. Technically we do not support El Capitan, however this version does not experience this particular error. To be completely safe we recommend using Yosemite.
