Tweening on the server lagging?

I have tweening on a server script to change back ground colors and text sizes on a surface gui, but whenever I play the game the tweening lags and doesn't work well. I'm not sure if I would be able to put it on a localscript, would I have to put it on a localscript or is there no other way?

TweenService is lagging on the client because of a bad internet connection. The only way to counter this would be using a RemoteEvent to tell the client to play the tween. It is perfectly okay to use TweenService on the client.

If my answer solved your problem, please remember to mark it correct.
