How do I get certificate from certbot to work on Iphone Safari

I have added the certificate for HTTPS using certbot. On the computer it works great and it shows the "lock" in the url.

The issue is on the phone. When I am not connected to my home wifi, I get the error that a secure connection is not established. It also only works on some wifis.

However, when I use other Iphones it will work to open the website but it shows the warning sign as it is not secure.

is there a problem with how I installed something? Is safari just blocking it? Why does it work on some iphones and not others?

Thank you,

Might be worth trying https://www.ssllabs.com/ssltest/ to see what that says for your domain. The "Handshake Simulation" results will tell you which browsers your SSL configuration is compatible with.

To support older insecure/unsupported browsers, you may need to reconfigure your web server. https://ssl-config.mozilla.org/ is a handy tool and, for example, with Nginx you need to select the "Old" option ("Compatible with a number of very old clients, and should be used only as a last resort") to support Safari 8 or earlier.

It looks like the issue is IPV4 and IPV6 are configured differently. Not sure how to view the IPV6 to make sure it is configured the same.
