Nginx configuration for TYPO3 website in subdirectory - nginx

Question

I need to run a TYPO3 website on Nginx in a subdirectory of a domain: example.com/subdir.
The website is running well for normal pages, but not for pages with tx_news-records. As soon as I call a news detail page (example.com/subdir/detailpages/slug-of-news-record.html), I get the following error:
#1537633463 OutOfRangeException
Hash not resolvable
This is my Nginx config:
location ^~/subdir {
alias /var/www/html/subdirectory;
disable_symlinks off;
index index.php index.html index.htm;
try_files $uri $uri/ #subdir;
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
}
location ~* ^/subdir/fileadmin/(.*/)?_recycler_/ {
deny all;
}
location ~* ^/subdir/typo3conf/ext/[^/]+/Resources/Private/ {
deny all;
}
location ~* ^/subdir/(fileadmin/|typo3conf/|typo3temp/|uploads/|favicon\.ico) {
}
}
location #subdir {
rewrite /subdir/(.*)$ /subdir/index.php?/$1$is_args$args last;
}
location ~* ^/subdir/(.*$) {
return 301 /subdir/$1;
}
What is missing in my Nginx config and is there something in general which I need to approve?

Answer 1

After some trial and error I found the solution myself. The following configuration is working for me:
location ^~/subdir {
alias /var/www/html/subdirectory;
disable_symlinks off;
index index.php index.html index.htm;
try_files $uri $uri/ #subdir;
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
}
location ~* ^/subdir/fileadmin/(.*/)?_recycler_/ {
deny all;
}
location ~* ^/subdir/typo3conf/ext/[^/]+/Resources/Private/ {
deny all;
}
location ~* ^/subdir/(fileadmin/|typo3conf/|typo3temp/|uploads/|favicon\.ico) {
}
}
location #subdir {
rewrite /subdir/(.*)$ /subdir/index.php?$args last;
}
location ~* ^/subdir/(.*$) {
return 301 /subdir/$1;
}
As always, it was just a tiny little change.
location #subdir {
rewrite /subdir/(.*)$ /subdir/index.php?/$1$is_args$args last;
}
Changed to
location #subdir {
rewrite /subdir/(.*)$ /subdir/index.php?$args last;
}
