As per https://letsencrypt.org/docs/certificate-compatibility/ some of my users on iOS 9 can no longer access my website.

It looks like my site is using the legacy keychain with the expired root:

Is there a way in mup to force let's encrypt to use the modern keychain?

Looks like this would need to expose the certbot preferred-chain parameter as per https://github.com/electron/electron/issues/31212#issuecomment-931486784

sudo certbot certonly --nginx -d <domain> --preferred-chain "ISRG Root X1"

And also we'd need to be using an appropriate version of certbot which supports this parameter.
