We are running a streaming app, android chrome browsers, the entire screen goes blank

We are running a streaming app. In the last week, suddenly the stream videos have stopped playing on our website which is built in flutterflow. The videos run normally on android app and iOS browsers, but on android chrome browsers, the entire screen goes blank. We tested with other videos, and there work fine. Only the videos in CF stream throw the blank page error in web. Please help.
