@peopleinside Yes I did it multiple times. I am only able to install it through cli with this command php bin/console uvdesk:configure-helpdesk.

also sharing virtual host config .

server {
server_name www.abc.com;
root /usr/share/nginx/html/helpdesk/public;
index index.php;

server_tokens off;

location / {
try_files $uri $uri/ /index.php?$query_string;
}

location ~ ^(.+.php)(.)$ {
fastcgi_split_path_info ^(.+.php)(.)$;
fastcgi_index index.php;
fastcgi_pass php-fpm;
include /etc/nginx/mime.types;
include fastcgi_params;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
proxy_pass_header Server;
}

}

@peopleinside thank you for the reply.
the only configuration I changed is in the framework.yaml

handler_id: session.handler.native_file
save_path: "%kernel.project_dir%/var/sessions/%kernel.environment%"
cookie_lifetime: 172800
cookie_secure: auto
cookie_samesite: lax
#storage_factory_id: session.storage.factory.native

and its working.

and also not able install through web installer continuously getting below error on last step.

Getting 302 after login. Please see the screen shot below.
I will be very grateful.
