Clamping a physics constraint

I am attempting to make a grapple rope that you can swing with. Right now I am working on just getting the swinging working. At the moment I have a third person character that spawns an actor blueprint I created (on line trace hit) and attatches a cable component between the character and actor spawned. This looks perfect. The issue comes to the physics constraint. The “Hook” actor being spawned has a blueprint that fires at begin play setting its physics constraint component to target itself and the character. The constraints show in the editor as being linked but when the character leaps off of anything there is not constrained motion. Any ideas on where to look? Been working on this for two days now.
