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. 🙂 * Thread Starter [mfidelman](https://wordpress.org/support/users/mfidelman/) * (@mfidelman) * [13 years, 4 months ago](https://wordpress.org/support/topic/register_http_request_failed-4/#post-3414597) * Taking this public… results from compatibility test (which looks like everything is 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/](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.

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. * [daidaros](https://wordpress.org/support/users/daidaros/) * (@daidaros) * [13 years, 4 months ago](https://wordpress.org/support/topic/register_http_request_failed-4/#post-3414619) * Now it is working. * Thread Starter [mfidelman](https://wordpress.org/support/users/mfidelman/) * (@mfidelman) * [13 years, 4 months ago](https://wordpress.org/support/topic/register_http_request_failed-4/#post-3414629) * 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.
