This is very strange. It's somewhat hard to debug because some of the explorative queries I'm trying are timing out (I'd love to be able to poke around how you have this set up so I can try to fix the performance issues), but I believe you've got an empty default graph causing the empty query results (the service description says the default graph is empty), but data in named graphs which DESCRIBE is pulling from. Unfortunately, the service description doesn't describe the named graphs, and my attempt to get a list of named graphs timed out.
