Error 404 on image png

Hi, I use Gitea on OpenBSD, with nginx as proxy for gitea.
(see: git.huc.fr.eu.org)

My nginx config:

server_name git.huc.fr.eu.org;

access_log  logs/git.huc.fr.eu.org/access.log main;
error_log   logs/huc.fr.eu.org/errors.log;

# root /; not need!

if ($host !~ ^(git.huc.fr.eu.org|www.git.huc.fr.eu.org)$ ) { return 444; }
add_header Access-Control-Allow-Origin "git.huc.fr.eu.org" always;

location /.well-known/acme-challenge/ {
    rewrite ^/.well-known/acme-challenge/(.*) /$1 break;        
    root /acme;
}

location / {
#	proxy_pass http://localhost:3000;
	proxy_pass http://address_ip:3000;
}

location ~* ^.+.(avif|gif|ico|jpg|jpeg|png|webp)$ {
    ### not use $http_referer
    if ($host !~ ^(git.huc.fr.eu.org|www.git.huc.fr.eu.org)$ ) { return 444; }
}

location ~ /*.(jpe?g|gif|png|tiff)$ {

    access_log        off;

    add_header Cache-Control "public, must-revalidate, proxy-revalidate, max-age=31536000";
    add_header Pragma public;
    add_header Vary "Accept-Encoding";    

    expires           max;

    log_not_found off;

#    try_files $uri$avif_suffix $uri$webp_suffix $uri =404;    
	try_files $uri =404;

}

include /etc/nginx/conf.d/server/robots.conf;

But when I attempt to display image PNG, nginx reply with an error 404.
like: https://git.huc.fr.eu.org/hucste/pfstats/src/branch/main/pfstats.html.png

I attempt to disable both locations for image, but result the same problem.

Any idea?
