I got this error when I try to add a new server.
File Server tests:
api.cgi: ERROR (Can't connect to domain.com:80 (Permission denied) LWP::Protocol::http::Socket: connect: Permission denied at /usr/lib/perl5/5.8.8/CGI/Carp.pm line 314. )
upload.cgi: ERROR (problems with link)
htdocs URL accessibility: ERROR (should see XFS on link)
