I can't join any world and servers when use "Magic RGB Gloves / Shoes".

There is character that i just recently bought and build(Picture 1) but whenever i want to generate, join in worlds or server it doesn't let me, but when i use a normal character (Picture 3)i can join any worlds and servers. At first i thought it was because of the app i tried uninstalling and reinstalling it still doesn't work until when i changed my character(Picture 3) it suddenly work then i tried the character that i build(Picture 1) when i try to join any servers I'm stuck at "connecting to external server" and it disconnects. (Picture 2)
