HI  
I’ve just installed Metafresh on Ubuntu 16.04.06 via the installer. Went al OK, unfortunate that a newer version of Ubuntu is not yet supported.

When I open url url via a browser (tested with Firefox and Chrome) is only get a white page, noting else. If I use developer tools I see a 503 error. Any idea hot for fix this?

I can open the java client (slow loading), but it works.

Very strange… The 503 error is not gone… now I’ve got a some new error:

```
GET http://localhost/rest/api/login/availableLanguages net::ERR_CONNECTION_REFUSED

```

Anyone?
