So after I got booted off the server, had the 90000, 2002 and 1017 error for about two hours, I finally got back in, but when trying to communicate with my FC in the chat, like saying "hi all" or " i finally got back in yaay " it keeps saying that the command is incorrectly used

am I the only one experiencing this or is it some kind of bug? it is kinda annoying that I can't talk with my FC :/
