website 404 Not Found from some locations - apache

Question

I have migrated a website from physical server running apache to a virtual machine running nginx.
When I go to website direct link, website is up : http://www.via-ap.com
but when I go to Google and if I click on website on right panel, I get a 404 error.
see below :

I did these tests from many browsers and from private mode.
my default nginx vhost conf is :
server {
server_name _;
listen 80 default_server;
listen 443 ssl default_server;
ssl_certificate /etc/nginx/ssl/nginx.crt;
ssl_certificate_key /etc/nginx/ssl/nginx.key;
return 404;
}
and then each website have his own conf like this below :
server {
listen 80;
listen [::]:80;
server_name website.com;
return 301 https://www.$host$request_uri;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name www.website.com website.com;
root /home/website/www/;
index index.html index.htm index.php;
access_log /var/log/nginx/website.access_log;
error_log /var/log/nginx/website.error_log info;
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php7.2-fpm-website.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
include /etc/nginx/conf/website.conf; /* file where strict transport security headers are defined */
ssl_certificate /etc/letsencrypt/live/website.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/website.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/website.com/chain.pem;
include /etc/nginx/conf/ssl.conf;
}
Do you know why?
Thanks

Answer 1

solution found.
on first server block (listen 80)
as you said first, I have added www.website.com in addition to website.com
then I have replaced return 301 https://www.$host$request_uri; by return 301 https://$host$request_uri;
