ERR_CONNECTION_REFUSED on nginx Raspberry Pi Home Server - ssl

Question

Basically, I have created a site and purchased an SSL certificate. Everything worked fine, I linked up the certificate in the config of the site, but then it suddenly stopped working. My linked site configuration, where I replaced my site with 'example.com', is as follows:
server {
listen 80 default_server;
listen [::]:80 default_server;
return 301 https://example.com$request_uri;
}
server {
listen 443 ssl;

}
}
Now, my site doesn't even work on a local IP address (192.168.1.x). Can someone please offer a solution?
Thank you.
