Hello. I have a problem. I don't know if this is a bug. I bought Minecraft from the official website. When I try to enter a hypixel server, I get the string, Login failed: null. When I entered another pvp server, the following message appeared on the chat: Logged in with Non premium. Before I bought premium Minecraft, I was playing non premium and had the same nick as premium mc. Please help. Version: blazing pack 1.8.8. Greetings
