I ran this command:
Safari 10.1.2 running on Mac OS 10.10.5 (Yosemite) will not load the page due to SSL error. From what I have read (maybe outdated?) this browser version should be supported. What are the current minimum requirements for MacOS/Apple?
It produced this output:
Failed to load resource: An SSL error has occurred and a secure connection to the server cannot be made.
My web server is (include version):
Apache 2.4.46
The operating system my web server runs on is (include version):
CentOS, kernel 4.14.146-225.ELK.el6.x86_64
My hosting provider, if applicable, is:
Bluehost
I can login to a root shell on my machine (yes or no, or I don't know):
No
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
86.0 (build 27)
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
n/a
You'll have to contact BlueHost support for this. This isn't an issue with the Certificate, but how Apache is configured to use the certificate.
The LetsEncrypt certs are cross-signed by IdenTrust, which is in the macos trusted root store until at least as far back as 10.9; but likely further back: (see https://support.apple.com/en-us/HT202858 )
For issues like this, you can use a SSL compatibility checking service:
As you can see on that, Apache doesn't want to work with Safari 6-8 due to handshake errors.
Thank you all for the replies, I will follow up with Bluehost.
'Can you show a full picture of the error message'?
Unfortunately no - I am tag-team debugging this issue remotely with a friend who has a Mac platform device. I do not have one myself, which makes it a bit hard to make progress on issues like these.
