Internal Server Error

Looking back at those error logs you shared, here's what I think is going on:

The main errors seem to be:

• Failed proxy response from the mod_wsgi daemon process - likely a config issue with mod_wsgi
• Oversized response headers from the Django app - could be bad header settings in Django views/middleware

Alright, here are some steps I'd recommend to troubleshoot and fix these issues:
1 . Restart Apache and Django app to clear any bad state:

sudo systemctl restart apache2 # restart Apache 
sudo systemctl restart gunicorn # or whatever you use to run Django

2 . Check mod_wsgi config:

• Make sure WSGIDaemonProcess points to wsgi.py.
• Verify WSGIScriptAlias also points to wsgi.py.
• Set WSGIPythonPath if needed.

3 . Turn on mod_wsgi logging to check for errors:

LogLevel info  
WSGILog /var/log/apache2/wsgi.log # log errors here

4 . Test Django standalone to see if it works:

python manage.py runserver # run dev server

5 . If Django works alone, focus on mod_wsgi. If not, look at Django app.

6 . Check middleware/views setting headers in Django. No huge headers.

7 . Try simple stuff wsgi.py that just returns "Hello World". Get that working through mod_wsgi first.

8 . Try adding limiting on IP's like 99.255.136.241 making excessive requests.

Check other logs for clues. Tweak configs accordingly. Taking it step-by-step to isolate where issues arise, then gradually building back up the config often helps pinpoint and fix specific problems.

The last time the site worked perfectly is when I ran:
python manage.py runserver 0.0.0.0:8000 (I left port 8000 open!)
After that I ran the following commands:
sudo apt-get install apache2
sudo apt-get install libapache2-mod-wsgi-py3
cd /etc/apache2/sites-available/
sudo cp 000-default.conf src.conf
sudo nano src.conf

sudo chmod 664 src/db.sqlite3
sudo chown :www-data src/
sudo chown -R :www-data src/media
sudo chmod -R 775 src/media

Does anything stick out as a mistake, or if I need to install additional software?
Thanks.

Sorry! The Alias /static did not paste correctly. It is in the same format as Alias /media above.
