Activating the JetPack WordPress plugin when running on Heroku?

Question

I get the following error when attempting to activate the JetPack plugin on my WordPress instance I have running on Heroku.

Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host. Operation timed out after 15000 milliseconds with 0 bytes received

I found a claim that Heroku blocks this type of business-to-business traffic but couldn't find any documentation to support the claim.

Answer 1

So far I've found two ways to solve this:

1) The quick and dirty way (worked for me, but more a hack than a solution): Push your Web Dynos on Heroku to 2, connect JetPack, and then put the Dynos back to 1 or 0.

2) On the official Jetpack site: customize httpd.conf to allow for more concurrent connections:

Hope that helps!
