How to do IP canonicalization with Nginx and Certbot

I have multiple services running on my server which will be accessed via nginx and encrypted by certbot. If i want to acess my service with my http://example.com, I get redirected to http(s)://example.com, which is great.

However, if I type in my IpAdress:Port I wont get redirected to my domain. This is my abc.com file in /etc/nginx/sites-enabled

server {
server_name abc.com; #example: mysite.xyz
#access_log /var/log/nginx/<servicename>.access.log;
#error_log /var/log/nginx/<servicename>.error.log;

location / {
        proxy_pass http://127.0.0.1:9000; # here you define the address, which is used by nginx to access your service
        proxy_http_version  1.1;
        proxy_cache_bypass  $http_upgrade;
        proxy_set_header Upgrade           $http_upgrade;
        proxy_set_header Connection        "upgrade";
        proxy_set_header Host              $host;
        proxy_set_header X-Real-IP         $remote_addr;
        proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host  $host;
        proxy_set_header X-Forwarded-Port  $server_port;
} # this is the port you use to access the proxied service

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/abc.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/abc.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = abc.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

server_name abc.com;

listen 80;
    return 404; # managed by Certbot

}

Can someone tell me or point me into a direction what I need to change in my abc.com file in order to redirect also requests via IpAdress:Port to https://example.com

I am grateful for any help!

Edit: I have made my services reachable via localhost which solved my problem. Thank you all for your contributions!

Welcome to ServerFault.

You don't have to edit the existing file that may be modified by Certbot in the future.

Instead, in /etc/nginx/sites-enabled, please create another file (for example, with the name ip.conf), with the following content...

server {
    listen 80;
    server_name 127.0.0.1;
    return 301 https://example.com$request_uri;
}

In the above code, please replace 127.0.0.1 with the actual IP address of your server and then replace example.com too.

Change one of the last lines to

listen 80 default;
