502 Bad Gateway nginx/1.18.0 (Ubuntu)

Hi @dailychoices2020,

In order to fix the issue, I’ll recommend you checking the Nginx error_log. This error_log will provide you with the exact reason behind the 502 Bad Gateway error you received on Nginx.

If unsure, you should be able to find where your error_log file is located from your /etc/nginx folder in the configuration file of your domain.

If you find the error, post it here so that we can give some suggestions on how to proceed.

Hello @dailychoices2020,

Thanks for reaching out. A 502 Bad Gateway Error is a general indicator that there’s something wrong with a website’s server communication. Since it’s just a generic error, it doesn’t actually tell you the website’s exact issue. I recommend you to first check the Nginx error logs for more information.

/var/log/nginx/error.log

Hope this helps!
