My child's mother is going against court order, what can I do?

I'm in the navy, I've been deployed to Japan and I haven't heard from my child's mom for the last two months. She moved changed her number and blocked me on all social media. I came back to ca for Christmas leave and haven't been able to locate her. She is supposed to notify me of any moves and change of number, she's supposed to let me Skype with my daughter and I'm supposed to get her 3 weekends of the month plus holidays and I can not find her. I have to go back to Japan in four days and I don't know what to do as far as finding my daughter and getting her mom to follow our court ordered custody agreement. Is there anything I can do? I've already called the police and nothing came of it. In afraid I won't get to see my daughter again.
