HEAD request times out

I am trying to do HEAD requests against some URLs before doing the actual download, but the requests just times out. An example URL:

http://www.sunhotels.net/SunHotels.net/HotelInfo/hotelImage.aspx?full=1&id=528422

I have made a failing test here: https://gist.github.com/stigkj/fce1239ae09a3327b88bf134c77ef1d1

curl -I against the URL does not hang. OkHttp version is 3.9.0.

Disabling gzip makes it pass

    Request request = new Request.Builder()
            .head()
            .url("http://www.sunhotels.net/SunHotels.net/HotelInfo/hotelImage.aspx?full=1&id=528422")
            .header("Accept-Encoding", "identity")
            .build();

@wmjwmj828 Are you also making requests to www.sunhotels.net? This error is caused by a badly behaved web server, so doesn’t apply generally, just to this server.
