Q: Icloud won't stop asking me to unlock my Apple ID and reset my password eventhough it is not locked at all

Hi guys,

I have lost my apple id password but then I have found and recovered it back again. All is good with password and signing in icloud web. Except my Ip6, the one i mainly used. As I said above. Icloud in my ip6 keep asking me to unlock my apple id and reset my password. At first, I didn't know so I did what it asked me to do. Then, after answering security question and reset my password, it asked me again and again and again and I can't even sign out or turn off Find my Iphone eventhough I type the right password. I have tried sign in and sign out on my other ip4 and it worked normally. In Find my Iphone, it doesn't appeared my ip6 even though Find my Iphone is on. Can anyone help me, please????
