Thanks for the link! Can you contact your hosting provider and explain to them that we are unable to access your blog via cURL, which is needed in order to use Jetpack on your site?
You can let them know we tested the following:
1. Check for access to xmlrpc.php via browser:
https://mythus.mythusmage.info/xmlrpc.php
That test returned “XML-RPC server accepts POST requests only.” which is a valid result.
2. Check for access via cURL by running the following command from the command prompt:
curl -i -H 'Content-Type: text/xml' --data '<?xml version="1.0&"?><methodCall><methodName>demo.sayHello</methodName><params></params></methodCall>' 'https://mythus.mythusmage.info/xmlrpc.php'
The cURL test returned the following invalid result:
HTTP/1.1 410 Gone
Date: Wed, 15 Apr 2015 22:33:18 GMT
…
The requested resource /xmlrpc.php
is no longer available on this server and there is no forwarding address.
Please remove all references to this resource.
Please provide the information above to your hosting provider so that they can correct the server settings to allow cURL access. Then, try to connect Jetpack once again.
