I would recommend reinstalling certbot and requesting a new certificate for your domain, starting over with the LetsEncrypt setup. Once you have the cert installed, update us here with your configuration if you’re still seeing issues with the redirect and we can assist in modifying it to meet your needs.

Ok I think it is back up after following your instructions, however trying to use a proxy pass to redirect traffic to my node app, which is currently failing, of course this should be an https request
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
tryfiles $uri $uri/ =404;
proxypass http://example.com:5007;
proxyhttpversion 1.1;
proxysetheader Upgrade $httpupgrade;
proxysetheader Connection ‘upgrade’;
proxysetheader Host $host;
proxycachebypass $httpupgrade;
}
