Materialdrawer: AccountHeader Profile Image not loading via URL

Hello. Maybe I'm doing something dumb here but I really can't make it to work and I don't know why.

I'm building my AccountHeader with some code like:

final ProfileDrawerItem profile = new ProfileDrawerItem().withName(mCurrentUserName)
    .withEmail(mCurrentUserEmail)
    .withIcon(mCurrentUserProfilePictureUrl);

AccountHeader header = new AccountHeaderBuilder().withActivity(this)
    .withHeaderBackground(R.drawable.drawer_header)
    .withActivity(this)
    .addProfiles(profile)
    .build();

I've also done this using the short way (passing a new ProfileDrawerItem straight to the AccountHeaderBuilder) but still no results.

I'm doing some Log.d()'s on the values that I'm passing and I'm pretty sure that they are not null. The name and email displays just fine but I'm having problems in getting to show the profile picture. It seems like it is showing a default image from my primary and accent colors and won't load the image in the URL that I passed.

Thanks for the help.
