I have a wordpress website and I was using Jetpack without any problems for almost an year until I updated it to version 3.0.0. After completing the installation, whenever I try to activate Jetpack I get the following error:

Your website needs to be publicly accessible to use Jetpack: site_inaccessible
Error Details: The Jetpack server was unable to communicate with your site [HTTP 406]. Ask your web host if they allow connections from

How do I fix this?

I have seen his issue before in which there was an issue with other plugins interacting with the WordPress installation that was causing the connection to fail. To troubleshoot the issue, I recommend disabling all other plugins and enabling them one by one to see if that helps. If not, try making a new installation of WordPress and installing Jetpack to it. From there, you can then determine what is different between the two installations and locate the culprit that is causing the issue.

I tried disabling all my plugins, but the error 406 still remains.

Another solution may be to disable mod_security as well. If that doesn't work, try replicating the issue on a clean WordPress installation.

Disabling mod_security didn't work either.

Have you attempted to replicate the issue with a clean WordPress installation? Sometimes core files can be modified which can cause this issue.
