You want to connect jetpack plugin with wordpress.com but keep giving
you this 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 403]. Ask your
web host if they allow
connections from
WordPress.com. If you need
further assistance, contact

WHAT IS THE CAUSE OF THIS ERROR AND HOW CAN YOU SOLVE IT?

Causes:

The
xmlrpc.php had been blocked
on the server level due to the
increased number of attacks
and that was causing the
error.

Solution: edit the
.htaccess file and add a new
rule to which will allow access to
the XML-RPC file only from the
Jetpack.

The code is : <FilesMatch "xmlrpc\.php$">
Allow from 192.0.82.250
Allow from 192.0.83.250
Deny from All
</FilesMatch>

1. You need to access the .htaccess
file. Therefore sign-in
into your Cpanel
2. Look for File
Manager under the Files section.
3.
Click on the File Manager, and it
will show you a window with options.

4.
Check the Web Root (public_html/
www) and put a mark on the
Show Hidden Files (dotfiles). Notice:
.htaccess is a dot file and is
usually hidden in the file
manager.

5. Select the .htaccess
file from the list of the files that open up in a new window in your
browser.

6. Click edit from a new window that
appear.
7.
Another tab will open. Add the following code : <FilesMatch "xmlrpc\.php$">
Allow from 192.0.82.250
Allow from 192.0.83.250
Deny from All
</FilesMatch>

8. Click Save. Your
Jetpack should work or connect now.
