Flask or Requests is Hanging unless timeout is specified, and hangs until the specified timeout
I'm on a new computer and running into a strange issue:
requests without the
timeout parameter simply hangs forever.
timeout parameter results in the request hanging until the value in
timeout has passed; for example, if
timeout is set to 2, the request hangs for two seconds; if
timeout is set to 10; the request hangs for 10 seconds.
Using Firefox or Postman or etc. doesn't result in this behavior.
I'm on Python 3.6.5 using requests 2.19.1.
import flask app = flask.Flask(__name__) @app.route('/') def home(): return 'hello' app.run(host='localhost', port=8080, debug=True)
import requests # This is instant requests.get('http://localhost:8080/', timeout=0.1) # This hangs for 2 seconds requests.get('http://localhost:8080/', timeout=2) # This hangs for 10 seconds requests.get('http://localhost:8080/', timeout=10) # This hangs forever without a `timeout` param requests.get('http://localhost:8080')
Using Firefox or Postman results in an instant response, so I figure it has something to do with
On my old computer, I cannot replicate this behavior with the same versions of Python and requests.
Incidentally, when I first loaded this new computer about a month ago, I did not have a problem.
After about three hours of debugging, I restarted my computer and the problem went away. I do not know the root cause.
