Jetpack IXR -32300: transport error

I’ve been using Jetpack for over a year now with no problem. A few days ago I had to deactivate all my plugins to fix and error and afterwards when i reactivated Jetpack I could no longer connect to wordpress.com.

I received the following message ‘Error Details: The Jetpack server was unable to communicate with your site https://www.mysite.net [IXR -32300: transport error: http_request_failed Recv failure: Connection reset by peer]’

I looked at the Jetpack Debugger Center and it said
It looks like your site can not communicate properly with Jetpack.
