I have a problem with my most recent openshift gear , i get the python error errno 13 , Permission denied. I have checked around on here and found that most people who have gotten the same issue have just forgot the if __name__ == "__main__": statement before the app.run(), but i still have the same issue. According to the log on openshift, the error seems to be rooting from the socket.py built in to python.
This is my second gear on openshift and both this and my first one is built using flask. The first one works just fine but my second one wont work ...
This is the error message I get in the python log from openshift:
* Running on http://127.0.0.1:5000/

EDIT 2:
So i changed the ip to OPENSHIFT_PYTHON_IP but the errorlog looked exactly the same. This is my wsgi.py code
#!/usr/bin/python
import os
virtenv = os.environ['OPENSHIFT_PYTHON_DIR'] + '/virtenv/'
virtualenv = os.path.join(virtenv, 'bin/activate_this.py')
try:

What port/ip address are you using? You must bind to port 8080 of your openshift ip address, you can't bind to 127.0.0.1, it is not allowed.

I've written this code and then ran it via the CMD. However when I ran the code this occurred.

Now I asked my professor but he's unfamiliar with the issue himself. I searched stackoverflow and I tried to disable my firewall but that didn't seem to help. Any suggestions? Is it an administration issue perhaps? My original code is below.
from bottle import route, run, static_file
#route('/')
def index():
return static_file('webpage_01.html' , root= 'C:/Users/Owner/Desktop/BottleWebApp')
run(host='localhost', port = 80, debug=True)
Does this problem go away when you try port 8000 instead of 80?
You're trying to bind to port 80. I don't know Windows, but on Linux your code would fail because port 80 (like all ports below 1024) is privileged--only root can bind to them. That's why you'll see most tutorials and web framework defaults use a high port number, typically 8000 or 8080.

I have developed a flask based app which is running successfully at my local machine / network.
I deployed it to an AWS EC2 instance. Started it like this:
flask run --host <private ip within AWS>
but when I tried to access an implemented API through Postman, I got following error in Postman console:
Error: connect ECONNREFUSED <IPv4 Public IP within AWS>
Noticed that it might be due to the fact that flask app typically runs on port 5000, however the EC2 has inbound rule of type http bound to port 80.
So I changed my flask code to:
if __name__ == "__main__":
app = create_app()
app.run(host='<private ip within AWS>', port=80)
And tried to run it like this in AWS ec2 instance:
python3 apiapp.py
However I got following stack trace while trying to run the app:

Am I missing anything obvious over here?
I was trying to use Linkedin API to scrape information about companies but i had a socket error:

socket.error: [Errno 48] Address already in use
My code is:
from linkedin import server
from socket import *
sock = socket()
sock.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
key = "key"
secret = "secret"
application = server.quick_api(key, secret)
Any suggestions how can i fix the problem ?
You could find and kill the process using the:
ps aux | grep python
Get the process id and kill using:
kill -9 PID
It will free the address.
OR you can try :
application = server.quick_api(key, secret, 5557)
As the title suggests, I am seeing this error when my flask app tries to run.
I am hosting the application locally using dev_appserver.
The error occurs when I visit the site and it tries to run the app. It appears that GAE is trying and failing to bind a socket for some reason.
I suspect that this may have something to do with OAuth2. Maybe it requires an SSL connection?
I don't even know where to begin solving this as none of the other posts about this are experiencing the same variation of the issue.
Edit: Here's a screenshot of the console confirming that the GAE server launches successfully on a different port; still doesn't resolve it

We have a tutorial that walks you through adding Firebase Authentication to your Python app running with Flask. Firebase Authentication is the preferred identity toolkit now. You can of course still use a pure OAuth2 flow, but Firebase Auth also provides multi-provider authentication if that's something you were considering adding to your app anyways. If you just want to dive into the sample's code its here on GitHub.
If you just want to stick with straight OAuth, you might want to look at your Flask code itself. Getting flask to run is pretty easy on App Engine. My guess is that you're calling some code that you don't need to (flask.run()) or you aren't importing your library properly (see appengine_config.py).

I'm trying to run a flask app on a remote server, so I can access it from other computers. The server has a public IP and I configured the flask to run on that IP. But when I run the script I get the following traceback
Note: I've removed the public IP from the traceback and my code.

You can only directly bind to an IP address that the server has been configured for; behind a router running Network Address Translation (NAT) your internal IP address will be different.
Either bind directly to that internal IP address, or use '0.0.0.0' to listen on all interfaces. You may still need to configure the router to forward a specific port to your internal server.
The IP you want to bind a socket to must be directly available on an interface of the machine. This seems not be the case here.
If you're behind a NAT: use port-forwarding
If you're using a VPN and the VPN adapter of the server is not always up, try using "0.0.0.0" as an address. Beware: It will listen on all interfaces available. Create firewall rules to block access via interfaces you don't want to listen to when using this.
