DPD's file uploader uses Silverlight, Flash, or HTML5 to provide feedback and reliability for uploading large files and selects the method based on what you have installed on your computer.
Please review the troubleshooting information below:
- Check to make sure you have the most current version of the Microsoft Silverlight installed in your browser. Silverlight gives the best experience of all the methods available and we highly recommend using it if available. An out of date Silverlight or Flash installation is the #1 cause of upload errors.
- 3rd party firewall and internet protection packages such as Zone Alarm, McAfee / Symantec / Norton internet security products, etc. may block the uploader's communication between your computer and DPD's server. This is the #2 cause of upload errors.
If you still have problems please check the following:
1. Wireless upload methods (including Wi-Fi and cellular / mobile / 3G / 4G / Wimax connections are notorious for dropping upload connections because of the packet loss and poor connection quality inherent with wireless internet. Try using a wired (ethernet) connection.
2. Some ISPs regularly reset upload connections. If your upload always resets at the same time (for example, at 50MB every time) then your ISP or IT department is probably resetting your upload connection automatically.
In most cases there is not much you can do about this. You may have more success by trying the FTP upload method or by going to a different location like your home, office, or a friends house to perform your upload. Connection resets are completely out of DPD's control.
