I'm creating a WordPress Site that is hosted on a secure server that can only be accessed from certain IPs and requires a proxy to let the server talk to other websites.
When trying to connect with WordPress.Com for Jetpack I got the following message:
Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host.
Received HTTP code 403 from proxy after CONNECT
I realised this means I need to let my proxy know it can talk to this address - but I was wondering if anyone knew the exact address that your site needs to connect to to connect to 'wordpress.com' so I can get it added to the proxy ACL?
