Laravel Object not found Error 404

The laravel project runs at another system with a fixed ip.

If I access the project on another computer via this line:

http://ift.tt/1SbR4T3

(changed to original ip for privacy)

it works so far but if I login the url does change to this:

http://ift.tt/1qTImzW

and I get the error

Object not found ... 404

The laravel project works if I call it locally via localhost....

I do not know why this is happening really big thanks for any help.
