I have changed the configuration file created by Certbot to listen on port 8080 instead of port 80, however, when I restart the NGINX service, I get errors relating to bindings.

server { listen 8080 default_server; listen [::]:8080 ipv6only=on default_server;
Restarting the service results in the following errors:
