SSL Cipher to cover old browsers

[musioc]

Hello
We are using Cloudlinux + cPanel + LSWS.
Recently we can not use mozilla ssl config for old browsers (https://ssl-config.mozilla.org)
And our websites have ssl error in old browsers (for example IE9 in windows 7)

Is there any ssl cipher to use in cpanel to resolve ssl issue in old browsers?

Do you use LetsEncrypt certificates for your websites? If yes you can read more about this here:

DST Root CA X3 Expiration and Let's Encrypt

Thank you for your reply
I knew this and certificates are updated.
This problem occurred for all ssl certificates (commercial and free such as RapidSSL , Certum, Comodo, LetsEncrypt...)
We use default cpanel ssl protocol and ssl cihper.

This problem only exists in older OS and browsers.

I really can't recommend lowering the security of the server for customers using outdated tools. That just seems like it will only lead to problems.

But I am wondering why google.com, microsoft.com, ... are loading in that old systems?
