I left my laptop three days ago. I don’t change anything on my server, even don’t access it. And My website gets 504 bad gateway today. What the hell?

×To help, we’ll need more info:
Apache2, or NGINX?
Either way, you’ll need to hop on the server, and grab logs from your web daemons log files (/var/log/apache2 for Ubuntu/Debian Apache2, /var/log/httpd for CentOS/Fedora Apache2, and /var/log/nginx/ for NGINX)
Once you have the logs, look for errors. They will tell you why the site is failing. If unsure, post the logs (just the errors) here.
Hi
Thank for your replying!
I’m using Nginx. Here is my log

My guess would be running service php-fpm restart will fix this.
