Code exiting after calling await client.ExecuteAsync(request)

Question

I am consuming an API and uploading data and check any update using Stream (Server sent events). Below is my code. I have created a async method and also called await while executing my request. where code is exiting and not proceeding to next step.

public static async void ResponseDataStream(string url, string Token)
{

    RestResponse DataResponse = null;
    var start = System.DateTime.Today.ToString("yyyy-MM-ddThh:mm:ss.fffZ");
    try
    {
        var options = new RestClientOptions(Settings.Default.API_BaseURL)
        {
            MaxTimeout = -1,
        };
        var client = new RestClient(options);
        var request = new RestRequest(Settings.Default.StreamURL, Method.Get);
        request.AddHeader("Authorization", "XYZ";
        //request.AddHeader("Content-Type", "application/json");
        request.AddHeader("source-system", "ZZZ");
        request.AddHeader("Connection", "keep-alive");
        request.AddParameter("start", start);
        DataResponse = await client.ExecuteAsync(request);
        ClsLogger.LogEvent("Reading Stream response." +DataResponse.IsSuccessStatusCode);
        if (DataResponse.IsSuccessStatusCode == true)
        {
            ClsLogger.LogEvent("Successfully connected to stream and reading content of the stream");
            var result = Newtonsoft.Json.JsonConvert.DeserializeObject(DataResponse.Content);
            ClsLogger.LogEvent("Data Stream Result is: " + result);
            if (result != null)
            {
                UploadData(Settings.Default.UploadURL, Settings.Default.FilePath, Token.ToString());
            }
        }
        else { }

    }
    catch (Exception ex) { throw ex; }
}

Can someone please help what I am missing here? Or why my code is exiting immediate after await function calls.
