Hi,
I have a Windows VPS with Plesk hosted by GoDaddy.
I am facing the issue with the older phones, they are unable to access my website.

The SSL Certificate is installed correctly.

SSL Checker

The certificate chain is working fine, but don't figure out how to fix the issue. GoDaddy support unable to assist in this regard.

Please advise what to do?
