Emulator gives failure response: Trust anchor for certification path not found - android-emulator

Question

I tried to search for this error a lot did not found any solution for it.
Details:
Made a request to API through retrofit, getting success response for the real devices but getting failure response if request is been made from android emulator.
public void loadPostsToDB() {
Call<List<Post>> call = mAPIServiceInterface.getAllPosts();
call.enqueue(new Callback<List<Post>>() {
#Override
public void onResponse(Call<List<Post>> call, Response<List<Post>> response) {
List<Post> posts = response.body();
new InsertPostAsyncTask(mDaoInterface,posts).execute();
}
#Override
public void onFailure(Call<List<Post>> call, Throwable t) {
Log.e("Failure Reason : "," "+t.toString());
}
});
}
In above code gives response, I checked through debugging, as per it, point hits on success when ran from real device but failure function debug point got hit if ran from emulator.
Below is the log which got printed.

Any suggestion? what might be causing this behaviour?

Answer 1

The issue got solved,
It was required change from server side for certificates.
