The FastCGI process exited unexpectedly - (Django iis hosting)

Question

I am following this tutorial to hosting my django application on windows IIS Manager. After following all steps from the tutorial I have got the following HTTP Error 500.0 - Internal Server Error

Is there any way to solve the issue?? I didn't find any solution for this...

I am using,

Python==3.10.0  
Django==3.2.8  
wfastcgi==3.0.0  
IIS 10.0.17763.1

I had this same issue (Error code 0x00000067) and have been beating my head against a wall for 24 hours. I am new to Windows servers, but have been deploying Django Apps on Linux servers for over a decade.

In my case, I had deviated from the Johnnyboycurtis tutorial you referenced in a few ways:

• I tried to install every python package in a virtual environment
• I did not install Python at C:\, but rather hidden under my user's AppData\local\Programs\Python dir (the default)

I am assuming that your app works when running the Django Development server (py manage.py runserver -> http://localhost:8000 ) your app looks as expected (when DEBUG = True in settings.py)

Fixing my code install meant taking the following steps:

• Navigating to C:\Users\MyUserName\AppData\local\Programs\Python, and following Johnnyboycurtis' instructions (but on Python310 instead of Python37) I added permissions for my AppPool to run Python.
• I had to install wfastcgi OUTSIDE of my virtual environment:
  • deactivate (if you have a python virtual environment activated)
  • py -m pip install wfastcgi

Note that I did NOT have to change any other settings that were assuming my virtual environment:

• web.config: 'scriptProcessor' still points to a python.exe and wfastcgi.py inside my virtual environment
• IIS FastCGI Settings 'Full Path' and 'Arguments' both refer to files in my virtual environment
