Adding my own experience   r   requests get download url   when I tried to download a file specified in the url  The error was HTTPSConnectionPool host  port 443   Max retries exceeded with url  Caused by SSLError SSLError  quot bad handshake  Error    SSL routines    tls process server certificate    certificate verify failed     quot      I corrected it by adding verify   False in the function as follows   r   requests get download url   filename  open filename   wb   write r content

It is always good to implement exception handling  It does not only help to avoid unexpected exit of script but can also help to log errors and info notification  When using Python requests I prefer to catch exceptions like this       try          res   requests get adress timeout 30      except requests ConnectionError as e          print  OOPS   Connection Error  Make sure you are connected to Internet  Technical Details given below  n           print str e                       renewIPadress           continue     except requests Timeout as e          print  OOPS   Timeout Error           print str e           renewIPadress           continue     except requests RequestException as e          print  OOPS   General Error           print str e           renewIPadress           continue     except KeyboardInterrupt          print  Someone closed the program     Here renewIPadress   is a user define function which can change the IP address if it get blocked  You can go without this function

Adding my own experience for those who are experiencing this in the future  My specific error was  Failed to establish a new connection   Errno 8  nodename nor servname provided  or not known    It turns out that this was actually because I had reach the maximum number of open files on my system  It had nothing to do with failed connections  or even a DNS error as indicated

What happened here is that itunes server refuses your connection  you re sending too many requests from same ip address in short period of time       Max retries exceeded with url   in app adobe-reader id469337564 mt 8   error trace is misleading it should be something like  No connection could be made because the target machine actively refused it    There is an issue at about python requests lib at Github  check it out here  To overcome this issue  not so much an issue as it is misleading debug trace  you should catch connection related exceptions like so   try      page1   requests get ap  except requests exceptions ConnectionError      r status code    Connection refused    Another way to overcome this problem is if you use enough time gap to send requests to server this can be achieved by sleep timeinsec  function in python  don t forget to import sleep   from time import sleep   All in all requests is awesome python lib  hope that solves your problem

just import time and add   time sleep 6   somewhere in the for loop  to avoid sending too many request to the server in a short time  the number 6 means  6 seconds  keep testing numbers starting from 1  until you reach the minimum seconds that will help to avoid the problem
