My friend owns a Minecraft server that I played on frequently, but suddenly I started getting timed out when I joined the server. It would sit on "Loading Terrain" screen forever until I eventually got timed out. Whenever I was able to join the server, I would just fall through the floor to -2500 until I got timed out again.
When I go to someone else's house and connect to a different Wi-Fi on the same device, and same Minecraft account, it lets me join just fine. However, all the other servers I have on my account work just fine, it's just this one server. (also all the other people on the server can join just fine as well)
I've tried many different solutions, uninstalling Minecraft and java twice, changing my computers ip address and DNS server, taking out my computer's wifi card and plugging it back in; none of which have given any results- with the same timed out messages and falling through the floor as before.
