picasso: Getting 504 Gateway Timeout from ResponseException

I’m having an issue on some devices on the same network when downloading photos from Flickr. Following your suggestion on a previous issue, here is how I’m calling Picasso:

OkHttpClient client = new OkHttpClient();
client.setProtocols(Arrays.asList(Protocol.HTTP_11));
Picasso picasso = new Picasso.Builder(c)
        .downloader(new OkHttpDownloader(client))
        .listener(new Listener() {
                    @Override
                    public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
                      exception.printStackTrace();
                    }
                  })
        .build();

And here is the full stack trace of the exception I’m getting:

com.squareup.picasso.Downloader$ResponseException: 504 Gateway Timeout

I tried playing with client.setConnectTimeout and client.setReadTimeout but they don’t seem to influence the downloader at all. The crash always occur before any timeout I set. Any ideas?

Thanks.
