1. It happens with all servers I try to join. It is also worth noting that on uncommon occasions, this issue does not happen, and can imminently join the server I choose.
2. I cannot load skins and realms before joining the server, as well as after, when it happens.
3. When I restart Minecraft, it is not fixed, however, I can temporarily fix it by signing out and back into my Xbox account.
4. Before, I was using a custom-downloaded skin. When I switch to default skin, it still refuses server connections, however loads skins and realms for some reason. I can still fix by re-signing in to my Xbox account.
Oh, I forgot to mention. The items and blocks look weird because I'm using the Halloween mashup textures.
