How to overcome the "Downloading settings from server failed" error

Background: 

Store settings on server allows clients the ability to store their Trader Workstation (TWS) settings/configuration on the cloud and retrieve them at anytime from another computer. This feature allows you to use the layout of a specific user on two or more machines.

In some specific circumstances, the operation which stores/downloads the settings to/from the cloud may fail and the following error message may appear shortly after the TWS has loaded on the screen:

 

 

 How to overcome this error message?

 The underlying causes of this message are usually the following:

  • ACCESS TO THE LOCAL MACHINE IS BLOCKED: A security setup, such as a firewall or antivirus, prevents the access of this computer to the cloud storage. This prevents TWS from accessing the remote server, thus disallowing the settings file upload or download. Recommended workaround: set up an exception on the firewall or antivirus in order to exclude the TWS executable file (c:\Jts\tws.exe) or the entire TWS folder (C:\Jts) from the real time security scan. The procedure to set an exclusion may vary, according to the software you are using, therefore we recommend consulting the user guide or the on-line documentation of your specific security program.
     
  • ACCESS TO THE REMOTE SERVER IS BLOCKED: A firewall or proxy service blocks the communication with the cloud storage through the network on which this computer is. In this scenario, you (or your IT / Networking departments, in case you do not have the rights for such an operation) can modify the firewall or proxy settings to allow the computer to communicate with the cloud server s3.amazonaws.com on the TCP port 443. For additional details about the hosts/ports which needs to be allowed for the proper TWS operation, please see as well the section "DESKTOP TWS" of KB2816. Please refer to the documentation of your specific software in order to create specific rules for your firewall or proxy system.
