Solving ISPConfig 3’s Mysterious Site Deactivation: A Quota Quirk Explained

Have you ever encountered a situation where your ISPConfig 3 control panel keeps disabling a website, even after you manually reactivate it? It’s frustrating, confusing, and can leave you scrambling for answers. I recently faced this exact issue, and after some digging, I discovered the culprit: resource quotas. In this post, I’ll walk through the problem, the troubleshooting process, and the simple fix that saved the day.


The Problem: A Disappearing Website

I was managing a client’s website hosted on a server running ISPConfig 3 when I noticed something odd. The site would randomly go offline, showing a “disabled” status in the control panel. I’d re-enable it, only to find it disabled again moments later. No configuration changes were made, and the server itself was running smoothly. What was going on?

At first, I suspected a server crash or a misconfigured cron job. But after checking server logs and …

Bad Request 400 in Nginx When Running Django using Gunicorn

Bad Request 400 in Nginx When Running Django using Gunicorn

The "Bad Request 400" error in Nginx when running Django with Gunicorn usually indicates an issue with the HTTP request that Nginx is forwarding to Gunicorn. Here's a breakdown of common causes and how to troubleshoot them:

1. ALLOWED_HOSTS Setting in Django:

  • Problem: Django's ALLOWED_HOSTS setting is a security measure that prevents requests with unknown host headers from being processed. If Nginx forwards a request with a host that's not listed in ALLOWED_HOSTS, Django will return a 400 error.

  • Solution:

    • Open your Django project's settings.py file.
    • Add your domain name or IP address to the ALLOWED_HOSTS list. For example:
    Python
     
    ALLOWED_HOSTS = ['yourdomain.com', '127.0.0.1', 'localhost']
    
    • If you're unsure of the host, you can temporarily use ALLOWED_HOSTS = ['*'] for testing, but do not use this in production.
    • Restart Gunicorn and Nginx after making changes.

2. Nginx Configuration Issues:

  • Problem: Nginx might not be …

(Q: I have a 8 CPU, 8GB RAM VPS server. How many separate Gunicorn instances with each one having 3 workers can I run?)

(A: A good starting point is around 5 Gunicorn instances, each with 3 workers. Gunicorn recommends (2 x $num_cores) + 1 workers. With 8 cores, that's 17 workers. However, since you have 3 workers per instance, you divide 17 by 3, which comes out to roughly 5.6. Given your limited RAM, starting with 5 instances is a safer bet. Always monitor your server's resource usage …
