Can you please try installing the Jetpack Compatibility Plugin so we can see some additional information from your site?

1) Download the plugin from https://plugins.svn.www.ads-software.com/jetpack/branches/jetpack-compatibility-test.zip
2) Upload the plugin to your site via Dashboard -> Plugins -> Add New.
3) Activate the plugin and go to Plugins -> Jetpack Compatibility Test.
4) Click the “Select All” button.
5) Send us results of the test via this contact form:
https://en.support.wordpress.com/contact/?jetpack=needs-service

Thanks!

Jeremy, Thanks for the quick reply. Just sent the results. (FYI: Some of us have shell access to our servers – downloading plug-ins to the desktop, then uploading them seems like a silly step – the control panel really should have an “install from URL” and/or “install from local file” option. ??

Taking this public… results from compatibility test (which looks like everything is working).

Well… I was about to upload a few more tests, but… this morning, everything seems to be working. I just registered.

I’m guessing there was something at the server end that was mis-behaving. Last nit, I installed a brand new copy of WP 3.5.1 and Jetpack 2.1.1 (both the latest) under Debian Lenny (oldstable). No other plug-ins except Akismet (no problem registering), and Debug Bar, with WP_DEBUG set to true.

Repeatedly, I got an error from wp-includes/class-http.php, line 921, indicating, not just
register_http_request_failed.
Could not open handle for fopen() to https://jetpack.wordpress.com/jetpack.register/1/
but also HTTP/1.1 400 Bad Request

I.e., my site was sending a transaction, the Jetpack server was receivign it, but it didn’t like the contents. So either, something was generating a bad transaction on my end, or something wasn’t behaving properly on the server. I’m guessing from this morning’s success that the problem was on the server.

So.. I guess this is resolved. Whatever you guys did on the server side – thanks!

Well, we haven’t made any changes on our end but I’m glad to hear you’re all set!

Do not hesitate to post here if it happens again.

I have same problem here. What can I do?

Jeremy… The problem was repeatable, then it went away, with no changes on my end. And since, the problem manifested as a server-generated 400 (bad request) error, our systems were talking. Perhaps you can take a look at the server log for failed registration attempts from either 207.154.13.52 (the vhost) or 207.154.13.48 (the primary address of the box). Perhaps you can tell something from the log entry.

Now it is working.

Sure does sound like something intermittent on the server or network side. Maybe one server in the Jetpack server pool, or something funny in the load leveler? Sure would be a good idea for someone to pour through the logs.
