Make your nginx error pages look great
mkdir -p /srv/http/default
git clone https://github.com/denysvitali/nginx-error-pages /srv/http/default
mkdir /etc/nginx/snippets/
ln -s /srv/http/default/snippets/error_pages.conf /etc/nginx/snippets/error_pages.conf
ln -s /srv/http/default/snippets/error_pages_content.conf /etc/nginx/snippets/error_pages_content.conf
Then add to each of your vhosts the following:
include snippets/error_pages.conf;
Example:
$ cat /etc/nginx/conf.d/plex.conf
server {
listen 80;
listen [::]:80;
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name plex.sv1 plex.sv1.lnet;
include snippets/ssl.conf;
include snippets/error_pages.conf; # <== This
root /usr/share/nginx/html;
location / {
include snippets/reverse-proxy.conf;
proxy_pass https://127.0.0.1:32400;
}
}
