Where I can find https://s3.amazonaws.com/ionic-io-static/xxxx.png

I found that the logo of my app was located at https://s3.amazonaws.com/ionic-io-static/xxxx.png
which is no more accessible from last few days.
I don’t have any idea about this path or directory over s3
It contains ionic-io-static. Seems image was uploaded through ionic.

Can anyone help me out or address me to find out this path.
