nginx config does not take action - nginx

Question

I'm trying to setup a basic nginx server. Usually I'm not working with nginx and I ran in to some issues I'm unable to wrap my head around.
I have a debain server with all the necessary things installed (like php, mariadb, ufw,...) and I want to run my website somewhat like this:
xxx.xxx.xxx.xxx -> /var/www/
http(s)://(www).lechner.io -> /var/www/domains/lechnerio/
I want both https and http and the domain with www and without pointing to the folder /var/www/domains/lechnerio and the IP Address pointing to /var/www/
First things first, only getting :80 working.
I have the following config setup:
server {
listen 80;
listen [::]:80;
root /var/www/doamins/lechnerio;
index index.php index.html index.htm;
server_name lechner.io;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/etc/php/7.3/fpm/php-fpm.conf;
}
}
however, when I now try to visit the IP the nginx welcome site is shown. When I access it via domain, it also shows the files from /var/www/ even though i reloaded everything. nginx -t is working. A link from /etc/nginx/sites-available/lechnerio to /etc/nginx/sites-enabled/
Any input very welcome!

try following

index index.php index.html index.htm;
server_name lechner.io www.lechner.io;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/etc/php/7.3/fpm/php-fpm.conf;
}
}
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/;
index index.html index.htm;
server_name _; # everything else
location / {
try_files $uri $uri/ =404;
}
}
