I am unable to reply to the original thread about the cert error but I see an error as well when visiting https://hubzilla.org:


hubzilla.org uses an invalid security certificate.

The certificate is only valid for demo.hubzilla.org

Error code: SSL_ERROR_BAD_CERT_DOMAIN

I tried "refresh permissions" which didn't change anything.
  
@Brian Christensen
Please re-check, added cert and redirect for https.
  
Works perfectly now.
