CodePudding user response：
A “connection reset” error usually means that the network is ok but the thing at the other end isn’t, or doesn’t want to talk to you, though with today’s “unclean” networks with proxies and firewalls and layering violations everywhere, there are probably more exotic causes as well.
In any case, I would not try to predict it (which is going to be hopelessly brittle) but deal with it when it happens by catching the exception.
CodePudding user response：
I don't know if it crashes because the internet connection. But if you want check if you have a internet cnnection you could ping a server for example 8.8.8.8 (Google DNS Server). If the command returns 0 it was sucesfull if it returns 1 it failed.
import os
response_code = os.system("ping 8.8.8.8 -n 1")
print(response_code)
