Files/Media Not getting Access publicly with URL in Codeignitator

I'm using a Codeignitator application named Perfex CRM and I'm having an issue to access its photos/files

when I'm logged in web panel I can access photos and all files with URL encryption

My question is I want to access these files/Media publicly without login to web panel but when I visit this URL without login it gives me this error

more to it i also tried to access files directy from folder 

Code:

 but it still gives same error 404.

What i have tried for this to access these file publically.

1. i have tried to change permission from htaccess file
   
   
2. i have tried to change all folder permission from 755 to 777 and also files permission from 644 to 777 but no luck.
