Hi, I had the same problem and it took me 3 days to figure that out! The cause of the problem is “windows Firewall” blocks “java”. Go and active your java both on “private” and “public” access in firewall setting. ---

Whatever block your java will be problematic. I am not familiar with OSX but you got my very same error. So something is preventing your java to show the content of the page and you have blank page. ---

Sounds like java is authorized on all my browsers, so i don’t understand the problem ---

I have enabled java in the browser via the Java Control Panel. I have enables Java plugins on all my browsers. Hence i wonder if that is the problem ? ---

Hi, We’ve seen this problem before with the embedded server. Is that how you’re starting up the stardog server? If so, you will need to specify the WEB\_ROOT option like so: ```auto Stardog aStardog = Stardog.builder() .home(new File()) .create(); Options aOptions = ServerOptions.defaults() .set(ServerOptions.WEB_CONSOLE, true) .set(com.stardog.http.server.ServerOptions.WEB_ROOT, new File(/webconsole/stardogweb).toPath()); aStardog.newServer().setAll(aOptions).bind(new InetSocketAddress(host, port)).start(); ``` ---

No, that was not the way. I manage somehow, and i am not fully sure. but got everything to work. ---

I know that java is enabled in your browsers but it needs access which sometimes is blocked by firewall. Try to give access to java through firewall instead of the browser.
