Steps to reproduce the behavior:

Everything was working just fine, then noticed I didn’t have the ability to create new tickets. Rebooted the webserver and nginx has failed to start.

From this message it seems you have configured zammad-railsserver twice. maybe you have 2 files there;
/etc/nginx/sites-enabled/zammad.conf
and
/etc/nginx/sites-enabled/zammad.conf.save
both containing the same configuration

removing that file and restarting nginx worked, but I have lost the ability to create new tickets for users. The chat is gone from the left hand side, the overview is gone, the dashboard is gone.

A default nginx configuration for Zammad should look like something like this:

github.com

zammad/zammad/blob/develop/contrib/nginx/zammad_ssl.conf

#
# this is an example nginx config for using SSL with zammad
# this can be adjusted to be used with self-signed, trusted ca and letsencrypt certs
# this example uses letsencrypt certs. replace all occurrences of example.com with your domain
# If using LetsEncrypt create letsencrypt certificate by: certbot certonly --webroot -w /var/www/html -d www.example.com
# create dhparam.pem by: openssl dhparam -out /etc/nginx/ssl/dhparam.pem 4096
# download LetsEncrypt x3 certificate by: wget -q https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem -P /etc/nginx/ssl
# you can test your ssl configuration @ https://www.ssllabs.com/ssltest/analyze.html
#

upstream zammad-railsserver {
  server 127.0.0.1:3000;
}

upstream zammad-websocket {
  server 127.0.0.1:6042;
}

server {
  listen 80;
