How to access matomo via a subpage on nginx Ubuntu - nginx

Question

I am using an Ubuntu 18.04.5 LTS webserver that is configured with nginx. The server is running and I can access any file on my mainpage example.com. Now I want to install matomo on the server. However, I can only manage to access the installation via my root url www.example.com. Whenever I try to move the Matomo-access to a subpage e.g. example.com/matomo/ my sever sends a 404 instead. I think I have made a mistake in creating a configuration setup for calling subpages, but I cannot figure out what went wrong. I am new to nginx and have spent the last 2 days testing for a solution. Any help would be highly appreciated. Please find my server.conf, as well as the matomo.conf below.
My server config-file is as follows:
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name www.example.com;
set $base /var/www/example.com;
root $base/public;
# SSL
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;
# security
include nginxconfig.io/security.conf;
# logging
access_log /var/log/nginx/example.com.access.log;
error_log /var/log/nginx/example.com.error.log warn;
# index.php
index index.php;
# index.php fallback
location / {
try_files $uri $uri/ /index.php?$query_string;
}
# handle .php
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
include nginxconfig.io/php_fastcgi.conf;
}
}
My matomo.conf:
server {
listen 443 ssl http2;
server_name www.example.com/subpage example.com/subpage;
access_log /var/log/nginx/matomo.access.log;
error_log /var/log/nginx/matomo.error.log;
## SSL
ssl_certificate /etc/letsencrypt/live/www.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/www.example.com/privkey.pem;
add_header Referrer-Policy origin always;
add_header X-Content-Type-Options "nosniff" always;
add_header X-XSS-Protection "1; mode=block" always;
root /var/www/example.com/subpage/matomo/; # path to matomo instance
index index.php;
## only allow accessing the following php files

include snippets/fastcgi-php.conf;
fastcgi_param HTTP_PROXY "";
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
}
## deny access to all other .php files
location ~* ^.+\.php$ {
deny all;
return 403;
}
## serve all other files normally
location / {
#try_files $uri $uri/ =404;
}
## disable all access to the following directories
location ~ ^/(config|tmp|core|lang) {
deny all;
return 403; # replace with 404 to not show these directories exist
}
location ~ /\.ht {
deny all;
return 403;
}
location ~ js/container_.*_preview\.js$ {
expires off;
add_header Cache-Control 'private, no-cache, no-store';
}
location ~ \.(gif|ico|jpg|png|svg|js|css|htm|html|mp3|mp4|wav|ogg|avi|ttf|eot|woff|woff2|json)$ {
allow all;
## Cache images,CSS,JS and webfonts for an hour
## Increasing the duration may improve the load-time, but may cause old files to show after an Matomo upgrade

add_header Pragma public;
add_header Cache-Control "public";
}
location ~ ^/(libs|vendor|plugins|misc/user|node_modules) {
deny all;
return 403;
}
## properly display textfiles in root directory
location ~/(.*\.md|LEGALNOTICE|LICENSE) {
default_type text/plain;
}
}

Thanks for the quick reply.
After further looking for solutions I have now done both: I created a subdomain and launched matomo under a subpage by adding the following code to the subdomain.config.
location /matomo {
root /var/www/subdomain.example.com/matomo;
}
I found this to be a great tutorial on creating subdomains.
