I have recently been trying to deploy my application to Heroku. I was following the documentation and everything but I'm getting this error now.
2020-03-12T21:46:36.154267+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=semsar-flask.herokuapp.com request_id=8c7e6604-97a5-4f5c-ae62-6c2edb73a4bb fwd="217.164.64.29" dyno= connect= service= status=503 bytes= protocol=https
This is my Procfile:
web: gunicorn wsgi: app
Wsgi.py:
from wbp import app
Did I make a mistake filling in those two files or what? Please do explain since I'm relatively new to this.
An H10 error could mean many possibilities and answering all solutions here would be tedious. You should also read here and see if any of those are helpful.
Also try to avoid empty spaces in Procfile. So try changing from this
web: gunicorn wsgi: app
To this
web:gunicorn wsgi:app
and see if it works.
For the app crashed h10 error check that your SECRET_KEY is added to Heroku. Also when logged in to Heroku, click on 'More' in the top right of the page and then 'Restart all dynos'. Both have helped me in the past with this specific error.

I am using python, heroku, gunicorn, and flask attempting to host a very basic web application. The URL provides me only with the error shown below:

Here are the errors in the error log, they are common, ive read as many stack overflow questions about this issue as I can find and none have helped.

Here are my files for reference:

import os
from flask import Flask
app = Flask(__name__)
#app.route('/')
def index():
return 'Hello World'
if __name__ == '__main__':
port = int(os.environ.get('PORT'))
app.run(host='0.0.0.0', port=port, debug=True)
Procfile
web: gunicorn --bind 0.0.0.0:${PORT} home:app
I have also tried
web: gunicorn home:app
with the following Procfile
import os
from flask import Flask
app = Flask(__name__)
#app.route('/')
def index():
return 'Hello World'
if __name__ == '__main__':
app.run()
I have tried as many changes as i can think of to the Profile and not one thing has helped. I am a software developer and have a decent understanding of things like this and am completely stumped. At this point the only thing that could potentially be affecting it is the requirements.txt Ive seen people say one of their packages was wrong but I have no idea how to determine if any of mine are wrong, after typing this I will most likely comment them out one by one and see if that can isolate the issue. here is said file:

gunicorn
I have tried with and without both the gunicorn and uwsgi, ive made attempts to use uwsgi instead of guniocrn though I dont think I was using it correctly nor think my pip install of uswgi worked, or if it was even needed. For more reference points, I am on windows, I am not using a virtualenv, and I have not changed any system variables because I could not find anyone saying how to change them or what to. All files are in the directory as well. If there are any other files that need to be seen please let me know, or if you have even remotely any idea what could help, it would be greatly greatly appreciated.
Thanks
I am trying to host a flask python application using gunicorn and heroku and am getting an application error.
I am attempting to create a web app to heroku.
It says that it deploys successfully but when I try to open it I get an error saying to check the console log.
There I find the following error code:
at=error code=H14 desc="No web processes running" method=GET path="/" host=name_name.herokuapp.com request_id=40cff699-28b5-4ea7-985b-c135dc8a526b fwd="174.16.132.201" dyno= connect= service= status=503 bytes= protocol=https
After searching around it appears to be a problem with my procfile. I have tried switching between 'web' and 'worker' but both give me the same error (above). Other peoples procfiles look very different to mine but I don't know enough about them to know what to change.
My current procfile:
worker: sh setup.sh && streamlit run name_name.py
Sample Procfile, note it must be capital P.
The app.py is the script filename.
web: sh setup.sh && streamlit run app.py
I'm trying to deploy my django website to heroku but I get an Application Error shown on the webpage. Looking at my logs using heroku logs --tail (what it tells me to do on webpage), I recieve an error

I followed the instructions from Django's docs.
Django 2.2.3
Python 3.7.3
Heroku-18
My webpage:
Make sure your put your Procfile at the root of project along with manage.py. Also make sure you pushed the code from your project root.
Bind port dynamically in your Procfile. Here's an example:-
web: gunicorn --bind 0.0.0.0:$PORT prremia.wsgi
$PORT is an environment variable. You must do scaling too.
Note: Make sure your project name exactly matches with <project_name>.wsgi in your Procfile.
Some time silly mistake is there when some one create Procfile as text file
so use the given command in your cmd to generate Prockfile:-
echo "web: python app.py" > Procfile

I finished a project (Week 8 CS50) and wanted to put it on the web. It works fine in the Cloud9 IDE and the localized web server. It's "application.py" and uses Flask (configured for me by CS50).
So I read up on deploying, and made several attempts to deploy on Heroku. Can't get it to work.

Procfile (Copied one from stackoverflow):
"web: python application.py"
Main application.py:
https://github.com/jamesdylangoldstein/sentiments/blob/master/application.py
All the files:
https://github.com/jamesdylangoldstein/sentiments
Steps to deploy:
1) Procfile contains:
web: gunicorn application:app
2) In requirements.txt type:
gunicorn
Based on the code you posted on GitHub, there are a few changes I would suggest to overcome this error:
Add the following to the end of your python program:
if __name__ == "__main__":
app.run()
make sure that app is defined (it seems to be in your case), and that you do not specify a port parameter in the .run() method. Heroku will crash if you define a port number in advance.
Make sure all dependencies are specified in requirements.txt. Make sure that your Procfile and requirements are properly stated as #James Goldstein defined.
Some web servers such as Azure require the python app to be named app.py by default. I do not know if this is the case with Heroku, but for some servers this could be an issue.
If your created your application using "create_app" factory so your Procfile shuld contains:
web: gunicorn -w 4 "my_project:create_app()"
I pushed my application to heroku and when I run heroku open I get an application error
I checked my logs and this was one of the error prints:
(2012-08-01T22:20:28+00:00 heroku[router]: Error H14 (No web processes running) -> GET wawacom-trotroapp.herokuapp.com/ dyno= queue= wait= service= status=503 bytes)
The app is a django app designed with a sqlite3. Can anysomebody help me?
https://devcenter.heroku.com/articles/error-codes#h14-no-web-processes-running
Looks like you need to scale up your web processes;
heroku ps:scale web=1
This should help. Follow the guide from Heroku. https://devcenter.heroku.com/articles/django
