output: The Internet connection to our FTP server was lost. Please try uploading your file again. If your file is under 20 MB in size, you can also upload your file directly through the Google Merchant Center data feeds page. If your file is larger than 20 MB, try splitting your data feed into multiple files smaller than 20 MB. The smaller file size will allow you to upload your files through your dashboard.
