PdfToHtml Conversion Gateway Timeout Error

I am getting gateway timeout error. The file size is 10.8 MB.
public async Task ConvertLocalPdfToHtml(string pdfFilePath, string outPutHtmlFile)
{
try
{
var wordsApi = new WordsApi(new Configuration { ClientId = Setting.AsposeConfig.ClientId, ClientSecret = Setting.AsposeConfig.ClientSecret, Timeout = Convert.ToInt32(TimeSpan.FromMinutes(10).TotalSeconds) });

            var fileInfo = new FileInfo(pdfFilePath);

            var requestDocument = fileInfo.OpenRead();
            var convertRequest = new ConvertDocumentRequest(requestDocument, "html");
           
            var actual = await wordsApi.ConvertDocument(convertRequest);                

            var fileStream = System.IO.File.Create(outPutHtmlFile);
            actual.CopyTo(fileStream);
            fileStream.Close();

            return new JobResult { success = true };
        }
        catch (Exception ex)
        {
            return new JobResult { success = false, message = ex.StackTrace };
        }
    }
