Python internal error Handling

I'm having issues with my program just closing at random stages and am not sure why.

At first, I thought it was because it was getting an error but I added an error handle. still for some reason it just closes after say a few days of running and no error is displayed. code below

import requests
import lxml.html as lh
import sys
import time
from clint.textui import puts, colored

API_URL = "http://urgmsg.net/livenosaas/ajax/update.php"

class Scraper (object):
    id_stamp = 0

    def __init__(self, timeout, recent_messages=True):
        self.timeout = timeout
        self.handlers = []
        self.recent_messages = recent_messages

    def register_handler(self, handler):
        self.handlers.append(handler)
        return handler

    def scrape(self):
        try:
            resp = requests.get(API_URL, params={'f': self.id_stamp}).json()
        except requests.exceptions.ConnectionError as e:
            puts("Error encountered when connecting to urgmsg: ", newline=False)
            puts(colored.red(e.__class__.__name__), newline=False)
            puts(" " + e.message)
            return

        if not resp['updated']:
            return

        old_id_stamp = self.id_stamp
        self.id_stamp = resp['IDstamp']
        # if old_id_stamp is 0, this is the first scrape
        # which will return a whole bunch of recent past messages
        if not self.recent_messages and old_id_stamp == 0: return

        # Pager messages are returned newest to oldest, we want to
        # process them oldest to newest
        frags = lh.fragments_fromstring(resp['data'])[::-1]
        for frag in frags:
            msg = PagerMessage(frag)
            for handler in self.handlers:
                handler(msg)

    def run(self):
        while True:
            self.scrape()
            time.sleep(self.timeout)

class PagerMessage:
    def __init__(self, fragment):
        children = fragment.getchildren()
        self.datetime = children[0].text
        self.text = children[1].text
        # channel starts with `- `
        self.channel = children[1].getchildren()[0].text[2:]
        self.response = 'CFSRES' in self.text
    def __str__(self):
        return "{} [{}]: {}".format(self.channel, self.datetime, self.text)

if __name__ == "__main__":
    scraper = Scraper(5)
    @scraper.register_handler
    def handler(msg):
        puts(colored.yellow(msg.channel), newline=False)
        puts(" [", newline=False)
        puts(colored.green(msg.datetime), newline=False)
        puts("] ", newline=False)
        if msg.response:
            puts(colored.red(msg.text))
        else:
            puts(msg.text)
    scraper.run()

Have I set this part out wrong ?

except requests.exceptions.ConnectionError as e:
                puts("Error encountered when connecting to urgmsg: ", newline=False)
                puts(colored.red(e.__class__.__name__), newline=False)
                puts(" " + e.message)
                return
