ControlPersist without ControlMaster
← All checksConnection persistence is enabled, but no setting can create a multiplexed master connection.
Why it matters
ControlPersist only works together with ControlMaster, so the configured duration otherwise has no effect.
How to fix it
Add ControlMaster auto in an applicable scope, or remove ControlPersist if connection sharing is not wanted. An unresolved Include suppresses this warning because it may enable ControlMaster.
