I am stuck with this error: OSError: [Errno 98] Address already in use

I tried every possible solution but still no luck. I am using oauthlib to authorize the user but when the user is redirected back to the website it get stuck and loads for ever.

However loading the website without authorization works fine.

my main app : if name =="main": path = "/home/kxchan86/project" if path not in sys.path: sys.path.insert(0, path) print(sys.path) app.run()

error:

I am also facing the same problem. I have followed pythonanywhere guidelines for flask deployment and ensured I only call app.run() in main without specifiying host & port. The app currently works fine locally and I get authorized and redirected back to the site with no issues.

You are not able run your flask app with app.run() on Pythonanywhere. Take a look at https://help.pythonanywhere.com/pages/Flask

I followed all the guidelines in https://help.pythonanywhere.com/pages/Flask but I am still getting the same error

Where do you get that error? The newest errors are at the bottom of your error log.

Yes at the bottom of the page

What's flow.run_local_server() in /home/kxchan86/project/Google.py doing? It looks like your web app is trying to start a local server, which is causing the error.

i am following the code from googleworkspace to connect to google calendar in python. The code to connect to google calendar via python can be found below: https://developers.google.com/calendar/api/quickstart/python https://github.com/googleworkspace/python-samples/blob/master/calendar/quickstart/quickstart.py It works flawlessly locally and also at hawkhost for example and I am sure there is a way to get it working on pythonanywhere

Just for clarity, are you trying to set things up so that your website can send people visiting it to a Google auth page from which they can allow access to their calendar so that your site can then add stuff to that calendar? Or are you trying to write a website that allows people to add items to your own calendar?

Basically the website allows certain users (already have access) to access a shared calendar.

Are they meant to be adding the items to the calendar via their own Google logins? Or via the same credentials for everyone?
