I have a public Salesforce community page hosted on a custom domain with a RapidSSL (Part of Digicert) SSL certificate.

I've checked the RapidSSL SSL certificate with SSL Checker, and everything is set up correctly.

It works for all the different browsers on Windows (10, 8.1, 8, 7, XP)

  1. Chrome
  2. Firefox
  3. Edge
  4. IE 11

But it just will not load on Safari on Windows (any version)

I get this error:

Safari can't open the page because Safari can't establish a secure connection

It does work on Safari on Mac OS:

  • Mojave
  • High Sierra
  • Sierra

But does not work with Safari on MacOS:

  • El Captain
  • Yosemite
  • Mavericks
  • Mountain Lion
  • Lion
  • Snow Leopard


  1. What is causing this can't establish a secure connection message?
  2. How can I fix it?
  • Can you check if you have anti virus installed. If yes, try disabling it temporarily.

  • @ManishG I am getting this across many computers, as well as the browser testing service called: Browser Stack (browserstack.com)

It sounds like there is a problem with the certificate.

This SSL Checker will help you diagnose problems with your SSL certificate installation:

    Does it also fail when viewed via Safari on a macOS machine?
