Still having issues deploying flask app on Godaddy shared hosting

I've been trying now for some time to deploy my flask app on a Godaddy hosting server. I have done extensive searches online and followed them but I'm still having issues. Right now my app is just displaying as ordinary html so I'm having things like {{my_var}} displayed on the page. My flask app works locally and this is the folder structure;

myApp folder, which contains static folder for css,javascript, and images, templates folder for my html, and the myapp.py and forms.py files come under the myApp folder

On my hosting server my folder structure is currently this; $HOME/public_html which contains the index.html and base.html (index.html inherits from this file for the header and footers), $HOME/public_html/cgi-bin which contains myapp.cgi, myapp.py, and .htaccess files.

I've created a cgi file and made it executable which is saved in the public_html/cgi-bin folder. The file is also made executable with 755 permission. These are the contents;

#!/home/username/public_html/cgi-bin/flask_app/bin/python
from wsgiref.handlers import CGIHandler
from myapp import app
import os
import cgitb; cgitb.enable()

os.environ["SERVER_NAME"] = "127.0.0.1"
os.environ["SERVER_PORT"] = "4000"
os.environ["REQUEST_METHOD"] = "GET"
os.environ["SERVER_PROTOCOL"] = "http/1.1"

CGIHandler().run(app)

Note the shebang on my files is the path to my virtualenv where I have flask installed. The version of python is v2.7 I also have my main flask app (myapp.py which is also executable and with 755 permissions) file with the routes and the contents are as follows;

#!/home/username/public_html/cgi-bin/flask_app/bin/python
import os
import sys

sys.path.insert(0, '/home/aofadero/public_html/cgi-bin')#path to myapp.py

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def home():
    return render_template("index.html")


if __name__ == "__main__":
    app.run()

This file is also in my public_html/cgi-bin folder. I also have a .htaccess file which has the following content;

AddHandler cgi-script .cgi .py
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(/home/username/public_html/cgi-bin/myapp.cgi)
RewriteRule ^(.*)$ /home/username/public_html/cgi-bin/myapp.cgi/$1 [L]

Now this .htaccess file is currently in my public_html/cgi-bin folder because if I place it in public_html folder, I get a 500 error message. The only time I don't get the error is when the .htaccess file is in the cgi-bin folder. Some of the research I've done say to place it in the cgi-bin folder, others say in the public_html folder. I find that it only works for me when it's in the cgi-bin folder. If I do ./myapp.cgi I get the following error;

Status: 404 NOT FOUND
Content-Type: text/html
Content-Length: 233

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>404 Not Found</title>...

Can anyone help me please because I've tried about everything I could on my own. Right now I'm just getting ordinary html and none of the flask components are showing. Thanks

You don't need to include the Python script in the public_html. If you go to the Cpanel main page and search for Python. From there, you can create a Python app which will let you direct your website to run the Python script.

Application root = path to the folder your python is stored. I stored mine in a Python folder in the root of the private html.

Application url = what URL should you need to put into the browser to get that script.

Application startup file = The name of your Python script.

Application Entry point = The callable object in your Python script (in your case, it would be app).

Please see the video here for a walkthrough of this process: https://www.youtube.com/watch?v=xFxL7Mvut6g&ab_channel=Hob-iZadeAdemEfendi

I have similar problems. I understand that an index.htm file must be placed at public_html, but when you try to do render_template("index.htm"), Flask will look for this file in the templates folder. The rendering is not actually executed. The index.htm file will always be displayed on the browser as a default page. Have you been able to find the solution ?
