I'm trying to deploy a flask app on IIS 10, but I got 500 error:

HTTP Error 500.0 - Internal Server Error
C:\Users\Administrator\AppData\Local\Programs\Python\Python36\python.exe - The FastCGI process exited unexpectedly

I'm using python 3.6 with wfastcgi 3.0.0 and I followed the web.config file template on https://pypi.python.org/pypi/wfastcgi, still no luck.

Anyone has an idea what's going on? Thanks in advance.

Yes sir.

Error 500 is an internal server error.
see: https://www.rfc-editor.org/info/rfc7231 for complete list of errors, and probable causes.
Not much to go on here, but this is the definition of that error:

Quote:The 500 (Internal Server Error) status code indicates that the server
   encountered an unexpected condition that prevented it from fulfilling
   the request.

Thanks Larz60, I understand that is an internal server error. There was a thread on stackoverflow saying wfastcgi module doesn't work with python 3.5, 3.6:

https://stackoverflow.com/questions/4274...expectedly

Above thread was posted a half year ago so right now I'm looking at https://pypi.python.org/pypi/wfastcgi and it looks like wfastcgi newer version supports python 3.6, which is my python version. But my question is, why am I still getting this error, am I doing something wrong there?

Is there anything meaningful in the IIS error logs?

Unfortunately no... I've checked the log files and event viewer. There is absolutely no related error message.
