My website is "Not-secure"

Hi, my partners and I have been trying to fix this issue for a week. Our SSL certificate expired, and we’ve been trying to generate a new one, but the certificate still doesn’t work and the website is not updating with the new certificate.

How can we resolve this?

We generated the SSL certificate using Let’s Encrypt through DirectAdmin, but it still doesn’t work and the website is not updating with the new certificate.

Also, the domain DNS records are not showing as secure.
