nginx syntax error - listen directive not allowed

Hello,

I have been following through a few different articles, but am now getting an error.

"listen" directive not allowed here...

listen [::]:443 ssl; # managed by certbot

After I set up certbot it was fine, so I’m not sure what else I have done to affect it.

The only change I have made to the file is adding WordPress bits as below.

    location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt { log_not_found off; access_log off; allow all; }
    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;

And…

    location / {
        #try_files $uri $uri/ =404;
        try_files $uri $uri/ /index.php$is_args$args;

Any help is much appreciated.
