Cannot download reportedly build RPMs

I have a local OBS installed from https://openbuildservice.org/download/. I have copied https://build.opensuse.org/package/show/home:geokraft4/helloworld to my OBS. I can successfully build it, but when I try to Download the RPM then it says "This site can’t be reached. localhost refused to connect." Is it because the webserver is not allowing it to read the /srv/obs/build/ directory? I cannot find "/srv/obs/build/" used in /srv/www/obs/api directory. Where would I config the OBS webserver to be able to access the built RPMs in /srv/obs/build/?
