Auth facade suddenly stopped working

I have an install that worked consistently until for some reason after install Auth facade stopped working. I did run composer dump-autoload, then php artisan clear-compiled .

But i'm still getting

PHP Fatal error: Call to undefined method Illuminate\\Support\\Facades\\Auth::user() in somePath/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php on line 207

I didn't change any code or the laravel version, so it must be something else. I'm running laravel 5.0.16.

Anyone have an idea where to start looking?
