current_site.txt is empty and I have done all steps in given link
this part is not present in my nginx.config file
instead there is something like this `server {
listen 80;
server_name
my-domain
;
root /home/khadija/frappe-bench/sites;
add_header X-Frame-Options "SAMEORIGIN";
add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload";
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";`
