the site can´t be reached

Hello dear community

Please help me!

For more than a week I have been getting this when I have tried to install LibreOffice in my MacBook pro:

http://download.documentfoundation.org/libreoffice/stable/5.1.1/mac/x86_64/LibreOffice_5.1.1_MacOS_x86-64.dmg

It says that the site can´t be reached

Is it working? What can I do?

Thanks for your replay!

Milton
