[CLPGithub]

When delete a website and re-create exactly same website name, I got error Bad gateway Error code 502, I didn't change any settings or cloudflare settings, and the previous site still online.

How to reproduce​

• delete a website
• re-create exactly same website name

This usually happens because when the site is deleted and recreated with the same domain, Nginx or PHP-FPM may still be using the old configuration or socket, so Cloudflare cannot get a valid response from the origin server and returns a 502 Bad Gateway error. In most cases, simply restarting the services fixes the issue:

systemctl restart nginx
systemctl restart php*-fpm

You can also run nginx -t to check the configuration and then systemctl reload nginx if needed.
