so me and my friends were playing on a server and I leave the server because I have to do something, come back, join, and this message pops up. I'm like, ok, they're probably going to be up in an hour or so. I close Minecraft, wait an hour or so, open it up, and the same message. My friends have joined and rejoined servers multiple times, so I'm 90% sure it's my pc. I log out of Minecraft, log back in, open Minecraft, and still the same message. help?
