is inaccessible

The bare domain,, is currently configured to use the certificate. That mismatch is making the site inaccessible, at least using Chrome. Thanks to HSTS, the browser won’t even let me ignore the cert issue. Encrypting will require a separate cert for the bare domain.

Kudos for adding encryption, though. I think every site should use https if possible.

It was the moment when I enabled HTTPS for the main domain. Through 1 hour I reverted back HTTP. Looks like you visited a site in this moment. Please take a look at my answer here Use HTTPS for community board - #9 by ivankravets

Working fine again once I cleared the HSTS data, thanks.
