Python - R10 Error (Download Timeout) & # 8594; Failed to bind web process to $ PORT within 60 seconds after launch

Question

I am deploying a python script in heroku that will send a request to another server after every 3 minutes .

Deployment is going well, but when I see logs , I got these errors .

Procfile

 web: python script.py --log-file - 

script.py

 import sys import requests from apscheduler.schedulers.blocking import BlockingScheduler sched = BlockingScheduler() @sched.scheduled_job('interval', minutes=3) def timed_job(): try: request = requests.get(url='https://royal-tag-services.herokuapp.com/api/sms-service/scheduler/') except Exception as e: print >>sys.stderr, 'scheduler request failed' sched.start()
