I'm trying to install Jetpack after a successful install, but Jeckpack throws an error about site not being publicly accessible:


Error Details: The Jetpack server was unable to communicate with your site [IXR -32300: transport error: http_request_failed Operation timed out after 15001 milliseconds with 0 bytes received]

Been checking Jetpack/WordPress support forums for some options, XMLRPC is enabled

XML-RPC server accepts POST requests only.

Trying curl to fetch the data & it's successful in making the connection

curl -i -L --data 'test' 'https://jetpack.wordpress.com/jetpack.register/1'

I don't use W3 Total Cache plugin, which seems to cause problems with many users.

How can I get it to activate?

I'm running on WordPress 3.3

You may not have enough processes running.

To test, try creating a file sleeper.php:

echo "Working fine\n";

And then run this from the cli:

curl -m 6 http://example.com/sleeper.php & curl -m 6 http://example.com/sleeper.php & wait

If there is only one process it will print out something like this:

Working fine
curl: (28) Operation timed out after 6001 milliseconds with 0 bytes received

Notes/credits: I received this test from my colleague Pyry Hakulinen while working on WordPress.com support. It should work as a basic test and starting point to troubleshoot the "Operation timed out after 15001 milliseconds with 0 bytes received" error.


I've fixed this removing the "maintenance mode" of my wordpress site. Working fine.
