Answer 1

Change that line. I think it’s case sensitive problems:

$this->group(['middleware' => ['auth'], 'namespace' =>'Admin','prefix'=>'ufs']

The namespace you put 'admin' and conveniently should be Admin..

Have to take care of it because in windows does not accuse error.

Answer 2

You created UFController and is calling UfController. See the F minuscule.

Answer 3

Suggested changes have been applied and solved.

$this->group(['middleware' => ['auth'], 'namespace' =>'Admin','prefix'=>'ufs']

$this->post('registration','Ufcontroller@registration')->name('Uf.registration');

Solved.
