Hi guys, I'm beginner with Pubsubhubbub so excuse me if this is a dumb question. I have a subscriber that subscribes to feeds on http://pubsubhubbub.appspot.com
When I use the sync mode I always get 409, when I use async I get 202 ... so I figured the subscription request is received by the hub but then I am never getting the verification request back from the hub? I've checked on http://pubsubhubbub.appspot.com/subscribe and it finds my subscription but says state: not_verified Confirmation failures: 4 Any ideas? As far as I can see my callback server is running fine (i.e. when I open the callback url in my browser, I can see that a GET request is received by the server ...)
