Minecraft hackclient nexus can't I use anymore?

I accidentally turned on the client with esp shader and had none and since that I can't help looking for server / single player joinen anymore

Deleting and playing legit would be something

If you have to hack in a game, think twice about whether you should play the game.

To be honest, bad luck if you can't connect because of that. Remove and play clean and you don't have such problems.
