I have been recently in touch with Riko. According to him, you should e able to access the Indonesian chapter now.
This is not an answer. This should be a followup comment on my answer.
Please provide more detail.... What URI are you trying to load? How is it failing? Any error message? Tried any different clients? Checked the network between you and it? Every little bit helps...Now you've added some details --
The DBpedia page on "Language and other Chapters" shows the contact person for id.dbpedia.org is Riko Adi Prasetya. Their email address can be found on the "Internationalization & Chapters" page. I believe you can also find them on Twitter and Linked-In.
