This error would occur when your SSL certificate has expired. You could add the -k flag to your curl command to ignore the SSL warning.

Or a better solution is to renew your certificate. You can follow the steps here on how to do that:

By removing the certificate you would no longer be able to access your domain/website via HTTPS on port 443, this is why you are getting the Connection reset by peer error.

Let's Encrypt is a Certificate Authority (CA) that provides an easy way to obtain and install free TLS/SSL certificates, thereby enabling encrypted HTTPS on web servers. In this tutorial, you will use Certbot to obtain a free SSL certificate for Apache on Ubuntu 18.04 and set up your certificate to renew automatically.
