jira-python DNS issue

Guy Matz I'm New Here Nov 29, 2017

Getting this error from jira-python after running it a lot:

 HTTPSConnectionPool(host='company.jira.com', port=443): Max
        retries exceeded with url:
        /rest/api/2/search?jql=project+%3D+NACRFT+and+status+%3D+%22Pending+Networking+Review%22+and+%22IP%2FPort+Updated%22+%3D+%22No%22+ORDER+BY+updated+DESC&fields=%2Aall&fields=comment&fields=changel

    [2017-11-24 16:02:51,307: WARNING/Worker-1]
    tasks.query_jira[ee5b2725-a31d-

But it's not temporary.  Any thoughts out there?  Thanks!!

P.S. - jira-python library version is 1.0.7

Hi Guy,

  • Are you using a proxy and if you bypass the proxy do you get the same behavior if you repeatedly run the jira-python code?
  • If you flush the DNS Cache on your computer system do you get the same results?
  • If you ping the hostname immediately after the failure what results do you get?

At this point I'm thinking there is some cached data may be incorrect.  Perform the test above and let me know the answers to those questions and we'll go from there.

Cheers,

Branden

Waiting for the problem to crop up again . . .  someone "resolved" the issue by rebooting the server.  This seems to indicate that your DNS cache hypothesis may have some validity, but I'd be very surprised if that were the case.  Will update shortly . . .

Hi Guy,

Thanks for the update.  Let me know how it goes.

Thanks again,

Branden
