Hi, This sounds similar to the "Common Installation Issue" listed here: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22500ServiceUnavailable%22fromtheUserInterface
Essentially, it's caused by the backend and frontend being unable to communicate. See the hints on that page for things to double check... it's likely in one of your frontend or backend configurations.

My problem is that my front-end can't communicate with my back-end because I changed the access URL (instead of http://localhost:4000, I use dspace.localhost). I've changed "dspace.ui.url" in local.cfg and in dspace.cfg but still nothing. Thanks for your help!
