Error Fetching RSS Feed (Response 0)

I've been trying to debug a Pipe that had been working for a long time, and that stopped working a week or so ago. I'm using a 'Fetch Feed' module to access http://export.arxiv.org/rss/astro-ph, and the module outputs:

'Error fetching http://export.arxiv.org/rss/astro-ph. Response: 0'

A scaled-down test version of the Pipe, that reproduces the above error: http://pipes.yahoo.com/pipes/pipe.info?_id=d9b1665620cfab3338a13f9fca904d5d

I saw elsewhere that this could be because the feed size changed - could this be the reason here as well? If yes, is there any plan to support larger feeds?

Thanks!

  • Hello,

    Your pipe is working - at least this simple one. you should post your real pipe, see what's wrong. Also, if you have trouble with fetch feed and have only one feed to fetch, try using fetch data instead. Almost same deal, but fetch data is more easygoing I'd say.

  • Hmm... That's strange. Looks like the problem is intermittent then. In my real Pipe, I use both Fetch Feed and Fetch Data for different purposes, and I was getting the same error. Anyway, hopefully this will remain working. Thanks for checking it out.

  • Nope. Got the same error again this week.

  • I tried a couple of other RSS feeds (http://www.npr.org/rss/rss.php?id=1001, http://rss.nytimes.com/services/xml/rss/nyt/InternationalHome.xml), and they seem to work fine with the Fetch Feed module. But at the same time, I'm able to see the problematic RSS feed's contents in Google Chrome: http://export.arxiv.org/rss/astro-ph

    Ideas?

    Thanks!

  • I just tried, and it works.

    next time it doesn't work try as soon as you get the error to copy the xml file of the rss and post it here (using pastebin for example) and/or check it for errors using the w3's validator: http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fexport.arxiv.org%2Frss%2Fastro-ph

    hope it gives some insights.

  • Same problem here with ArXiv rss feeds. I checked with w3's validator that the feed is in principle OK, but the following simple tests fails in Yahoo pipes:

    Any ideas welcomed.

  • Same here. My arXiv pipe worked for months, but for a couple of weeks I've been getting the same error (Response 0...). The pipe just linked by Alexandre is also failing now for me. All the sources I'm using check in w3's validator.

  • Alex, Muad,

    did you verify if the source feed: http://export.arxiv.org/rss/cond-mat

    was up or down?

    Thanks -Paul

  • Thanks for the reply Paul. I did check that the source feed was up. Just as a quick note to put things into context: although not mainstream, feeds from the arxiv are followed daily by most physicists worldwide and are hosted by serious organisations (used to be Los Alamos National Lab, now Cornell University). Although it can certainly happen, I have never seen this site being down.

    Strangely enough, after about two weeks, it is working again this morning. Feedbin unfortunately is not yet pulling any news from the pipe, but I guess/hope I just need to give it some time to react.

  • I noticed yesterday that the feed is once more outputting the error discussed above. There are still no errors reported by w3's validator but the simple test I posted before nevertheless fails:

    http://pipes.yahoo.com/cqedfeeds/simplearxivtest

    I just checked using feedbin that the source feed is up: http://export.arxiv.org/rss/cond-mat

    Any new ideas anyone?

  • [fyi] export.arxiv.org is down for me

  • hello again alexandre,

    I found out that arXiv has mirrors! Really simple to use with that: simply append ?mirror=fr to the rss feed URL. I think a good solution would be to fetch your feed from the current source, but also from one of the mirrors (closest one, or worst case scenario, of the second closest one in case the main URL simply redirects to closest mirror) and use the unique module based on guid. That way, one of the two should always be working.

    You can also fetch another feed from the same location by querying for the RSS 2.0 version of the rss, use ?version=2.0. If you want to choose your mirror and your version, then use ?mirror=fr&version=2.0

    all is detailed here.

    cheers!
