Hi, i been trying to connect to this server, it worked fine yesterday, some other servers work fine too, but now whenever i connect to this server it keep freezing at loading , and when i did manage to connect to it after dozens of tries, i disconnect few seconds later, and i get the message below. Can someone please tell me what is happening or at least tell me what is causing it, like is it my computer, the server or the Minecraft server. I tried to reinstall java, redownload World of Minecraft, and deleteing the .minecraft file in roaming file, none of it worked, the last thing i haven't try is reinstall OS. Thank you in advance for helping.
