Conflict with Jetpack

I’ve been using this plugin for quite some time, and it’s been a great, simple and reliable plugin, together with all my other plugins without any problems. Recently though I started seeing problems in another plugin, Jetpack, which reported errors in connecting to WordPress, and after some testing back and forth it appears these two are in some kind of conflict, turning off this plugin and Jetpack will work fine again, having both enable at the same time and all features except the config menu seemingly work, except it is extremely slow to open the page first time. Which is consistent with the Jetpack error that the problem is a timeout.

Jetpack gets quite frequently updated, and something in their new version is most likely the cause for the problems, however my question to you is whether this plugin is active, as it appears not to have been updated in a few years and I’d hate to have to remove it?

Best regards
