This error means Hominis and the website could not set up an encrypted connection at all, usually because the server is misconfigured or uses outdated security. Unlike a certificate warning, there is no way to continue: the page never arrived.
What you can do
- Reload the tile. Temporary server problems often clear up on their own.
- If many secure sites fail, check whether antivirus or security software is scanning encrypted connections, and update or turn off that feature.
- Check your Mac’s date and time.
- If only one site fails, the problem is most likely on its side. Its owner can check the server’s security settings.
