UploadFileAPI 在 hubspot 中突然停止工作

Question

 var client = new RestClient("http://api.hubapi.com/filemanager/api/v3/files/upload?hapikey=" + AppSettings.HubSpot.HapiKey);
            client.Timeout = -1;
            var request = new RestRequest(Method.POST);
            byte[] data;
            using (var br = new BinaryReader(attachmentFile.OpenReadStream()))
                data = br.ReadBytes((int)attachmentFile.OpenReadStream().Length);
            request.AddFile("file", data, attachmentFile.FileName, "application/octet-stream");
            request.AddParameter("folderPath", "/path");
            request.AddParameter("options", "{\"access\":\"PUBLIC_NOT_INDEXABLE\",\"ttl\":\"P12M\",\"overwrite\":false,\"duplicateValidationStrategy\":\"NONE\",\"duplicateValidationScope\":\"ENTIRE_PORTAL\"}");
            IRestResponse response = client.Execute(request);
            if (response.StatusCode != HttpStatusCode.OK)
                return 0;

我的 api 现在不工作了。我现在该怎么办？

错误消息“发送请求时发生错误。无法从传输连接读取数据：现有连接被远程主机强制关闭..”
