Facebook profile images dose not show on Android or on Web

I Made an app on android studio and also a web page by another developer. we use a facebook app for our login stuff and we exctract the user's profile image from it and show it on our webpage or app.

we use this : "https://graph.facebook.com/" + FacebookId()+ "/picture?type=large"

and we get the image and display it , everything worked until yesterday , for some reason today it dose not work, does anyone have an answer to it ? cause this dose not work on the website and not on android so im guessing its a facebook problem , anyone knows a way to get around it ?
