For the sake of completeness this is what I’ve tried:

– Made sure XML-RPC is enabled within wordpress admin using the plugin “Control XML-RPC publishing”
– Contacted hosting company to make sure xml-rpc isn’t blocked
– Deactivated and deleted JetPack plugin and reinstalled it multiple times
– Disabled all themes (used default Twenty Fourteen theme) and plugins apart from JetPack.
– I’ve checked that the SSL certificate has a rating of A or better and that it’s not self signed

EDIT:
– Tried all the steps mentioned here https://jetpack.com/support/getting-started-with-jetpack/troubleshooting-tips/

I know I’ve tried a few other things but I can’t recall what they were.

I’m abandoning the use of JetPack. Integration shouldn’t be this difficult to get working.
