Connections and certificates

“Warning: Security Risk” pages

Why Hominis stops before loading a site whose certificate it can’t trust, and what to do.

Before Hominis loads a secure (https) site, it checks the site’s certificate: a document that proves the server really belongs to the address you typed. When that check fails, Hominis shows a warning page instead (“Be careful. Something doesn’t look right.”), so nobody can read or change what you send.

Common causes

  • Your Mac’s date or time is wrong. Certificates are valid for a period of time, so a wrong clock makes good certificates look expired. See fixing clock-related errors.
  • The certificate expired or was issued for a different address. This is a problem with the site; try again later or let its owner know.
  • Something between you and the site is inspecting your traffic. Some antivirus software, company networks and public Wi-Fi portals do this. See certificates added by your organisation.
  • The site uses a self-signed certificate, which is common on home routers and development servers.

What you can do

  • Check your Mac’s date and time, then reload the tile.
  • Try again later, or from another network.
  • Don’t enter passwords or payment details on a site that shows this warning.
  • If you know the site and trust the network (for example, your own router), open Advanced on the warning page and accept the risk for that site. Only do this when you are sure.
