Hey there! A Friend of mine needs some help and he isn't registered on this forum and therefore I'm posting this for him. So let me explain he isn't able to log into the server(s) not a single one. He also claims that the download screen appears whenever he joins a server and the download screen doesn't close but he is able to read the chat.
He even furnished me with some screenshots: ( I've provided some links down below which shall lead you to the evidences captured by him. )
