I get the following error when I try to activate the JetPack plugin on my WordPress instance that I was running on Heroku.
Jetpack was unable to contact WordPress.com: register_http_request_failed. This usually means that something is incorrectly configured on your website. Operation completed after 15000 milliseconds with 0 bytes received
I found an expression that Heroku blocks this type of business traffic, but cannot find any documentation to support the claim.
