Image Repository - Share path not available

Image Repository - Share path not available

I'm getting an error that shows that the Share path not available, on the repository locations at the remote offices. 

I can put and pull images from the repositories at the central and remote locations, but I can't push the image from the central server to the sites. 
The Development system seemed to work properly, but when I'm setting up in the Test system the errors are presented.
I'd like to understand and fix this error before setting up on my Production system.
