Which is why these errors?

I think you need to give more of the console than that if you want people to help you, there's no error there, it's just people losing connection.
Check your console for real errors and provide us it.

 

To know this, we need an error. There's no error in what you provided.

 

Do you use BungeeCord?

 

To know why they lose connection we need an error...
