max retry exceeded with url in telegram bot

Question

I started writing a telegram bot in python. but when I run it after a while it returns an error:

Exception in thread updater: Traceback (most recent call last):   File "/usr/lib/python3/dist-packages/urllib3/connection.py", line 137, in

    (self.host, self.port), self.timeout, **extra_kw)   File "/usr/lib/python3/dist-packages/urllib3/util/connection.py", line 91, in create_connection
    raise err   File "/usr/lib/python3/dist-packages/urllib3/util/connection.py", line 81, in create_connection
    sock.connect(sa) OSError: [Errno 101] Network is unreachable

During handling of the above exception, another exception occurred:

I searched in the internet but I found nothing useful. can anyone help me to handle this error or solve it?

Answer 1

I was facing the same problem. What it actually means is that Telegram in this case is refusing your connection due to too many requests. Check it here (same question but with Itunes).

Try using a try-except to avoid this error message.

try:
    page1 = #whatever code
except requests.exceptions.ConnectionError:
    r.status_code = "Connection refused"

And most of it might be because you let it run but not write anything in the bot, so it goes "silent". If we "sleep" the program, that won't happen as empty requests won't be sent. Use sleep(timeinsec) function in python (don't forget to import sleep).

from time import sleep
