File Storage not working

Data is stored in my table and storage path. But it does not showing any image in my view page.? what is happening now. Did I make any mistake. Please check image src line.

My table fields are:
logo_id
company_name
company_avatar
created_at
updated_at

This is my blade file image tag code

<img class="profile-user-img img-fluid img-circle" src="{{ Storage::disk('public')->url($data->company_avatar) }}" alt="User profile picture">

Here is my controller
