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


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 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.

See KB2320 for instructions on transferring settings from one user to another


How to check and solve connectivity issues affecting the Trader Workstation (TWS)


The Trader Workstation (TWS) software needs to connect to our gateways and market data servers in order to work properly. Connectivity issues affecting your local network or your Internet Service Provider network may negatively affect the TWS functionality. In this article we will indicate how to test your connectivity using an automated connectivity test web page.


How to test the connectivity using the automated "IB Connectivity Test" web page?

1) Launch the Firefox browser and open this link with that browser: 
Note: due to browser specific constraints, the above connectivity test link will only produce consistent results on the Mozilla Firefox browser. If you do not have Firefox, you can download and install it form here.

2) Please wait until all the tests have been completed and results have been displayed. If you see "Success" as outcome for all tests, your connectivity to IB Servers is reliable at the present moment. No additional connectivity troubleshooting or configuration should be needed.

3) If you see "Fail" as outcome for one or more test/s, please click on the link "Fail" itself in order to display the "IB Network Troubleshooting Guide". That section will help you conduct some manual tests to identify the cause of the failure.

Note for Corporative environments and Proxy server users: the automated "Connectivity Test" page may return misleading results in case your machine is accessing the Internet through a Proxy server. This usually happens if you are connected to a company network. If this is your case, we kindly ask you to contact your Network Administrator or your IT Team and ask them to perform a manual connectivity tests towards the destination servers indicated in the table on the top of the IB automated "Connectivity Test" web page itself. The manual connectivity test should be conducted using destination TCP ports 4000 and 4001. Should they prefer to have the server list in another format or should they need to set up the firewall / IP Management rules, you can forward them this page.


When and how should I increase the memory allocation for TWS?

Java Virtual Machine memory allocation

The Trader Workstation is a Java-based application. As any other Java applications, it executes within a Java virtual machine (JVM) which manages the interactions between the program and the underlying Operating System (OS).

The memory (RAM) which is allocated by the operating system to the JVM constitutes the heap space. That is the area where all the class instances and arrays needed by the application are allocated. The heap space is created when the JVM is started and it is dynamically freed-up by the Garbage Collector (GC), the Java memory manager. When the need arises, the Garbage Collector is invoked to free up the heap space by unloading Java classes and other code structures no longer used by the application.

If the heap space is undersized, the Garbage Collector may not be able reclaim memory at the needed pace or may have to be called too often, draining the processor (CPU) resources. When this happens, the application may slow down, be unresponsive or even crash completely.

To ensure a smooth TWS run, it is therefore sometimes necessary to change the memory allocation, according to the layout complexity and the needs of the application itself.

In which case I should change the TWS memory allocation?
If your TWS layout contains a considerable number of elements (Analytical/Trading Tools, Chart windows, News panels, Watchlists, Layout tabs...) and your platform is slow or poorly responsive, you may want to increase the memory allocation in order to achieve better performances. If your TWS freezes or crashes, we also recommend increasing the heap space as the first corrective action to attempt. 
How much memory should I allocate to TWS?
In general we recommend to start with a conservative memory allocation and test the TWS performances with that set up. If the performances improvement is less noticeable then expected or not yet satisfactory, you can switch gradually to higher values until you find the best fit for your platform.
Please consider the following:
  • The memory you allocate to the TWS has to be available on your system. For details, please see Note 1. Allocation values above 2048 are not supported by 32-bit OS. For details, please see Note 2. 
Considering the above, we suggest to initially reserve 1.5 GB of system RAM the TWS, as explained in the guide below.
This amount of free memory is usually available on any modern computer and should be a good fit for most of the cases. Should you still notice slowness, freezing or crashes during the TWS execution, you can raise the value to 1792.
In any case, we do not recommend to set the value above 2048 since this will produce an unnecessary overhead and may thus even decrease the overall performances of the application.


How can I change the memory allocation for the TWS?

Please follow one of the links below for the instructions, according to the Operating System and TWS release you are using

     Any Operating System

1. Available system RAM
In order to check the amount of available system RAM on your computer, you can:
 - on Windows: use the key combination CTRL+SHIFT+ESC to start the Task Manager, click on the tab Performance and look for the "Available" Physical Memory. This will tell you the amount of unoccupied RAM in MB (1024 MB = 1GB)
- on Mac OS: Open Finder, go to Application --> Utilities and open Terminal. In the terminal type the command:
sudo purge
and press Enter. The system may ask you to enter your Mac user password. Enter the password. Once the command has completed, type the following command:
top -l 1| grep PhysMem
The "unused" value will tell you the amount of unoccupied RAM in MB (1024M = 1GB)



 2. Limitations of 32-bit Operating Systems
Please notice that 32-bit Operating Systems can normally only address a maximum of 2 GB of RAM per process (see table below for details). Because of this OS architecture limitation, if you have a 32-bit OS, the maximum memory allocation for the TWS must not exceed 2048 Mb.


3. Error: "Could not create the Java Virtual Machine"
This error may be displayed upon TWS startup if you set the memory allocation to a value higher than the available RAM of your system or if you set it higher than 2048 on a 32-bit Opertaing System. To overcome the error, you would need to decrease the memory allocation to a lower value using this procedure

Use cases where assistance with system access is required


Please click on the use case below which best describes your login issue for guidance as to how to proceed:

I. No Access to Account Management or TWS

1. I forgot my User Name and/or password

2. I am temporarily without possession of my security device

3. My security device is lost or damaged

4. My temporary passcode has expired

5. My on-line security card has expired


II. Partial Access (Account Management only)

1. I am able to log into Account Management with my temporary passcode but not the trading platform


III. Full Access to both Account Management and TWS

1. I am in possession of my security device and wish to activate it.







  1. I forgot my User Name and/or password

For security purposes, all requests for assistance with a User Name and/or password must be initiated via telephone and require prior verification of the caller’s identity. Click here for a list of IB’s regional Customer Service center contact numbers.


  1. I am temporarily without possession of my security device

If you are temporarily without possession of your security device, interim access may be provided by contacting your regional Customer Service center via telephone where, once your identity has been verified, you will be provided with a temporary passcode.   

This temporary passcode is a static alpha-numeric code which replaces the random code supplied by your security device and which will provide full access to both Account Management and the trading platforms for 2 days.  Should a lengthier period of interim access be necessary and to obtain enhanced protection, it is recommended that you use the temporary passcode to log into Account Management and print out the on-line security card which will operate as a replacement to your security device for up to 3 weeks.   

After the expiration of the temporary passcode or on-line security card, or if you regain possession of your security device beforehand, you will need to log into Account Management and select the menu option to re-activate your security device.


  1. My security device is lost or damaged

In the case of a lost or damaged security device, you will need to contact our Customer Service center to arrange for a replacement and to provide for interim access. As the time frame for shipping a replacement device may range form 3 to 14 days depending upon your country of residence, interim access is provided via an on-line security card. The on-line security card may be retrieved for printing or saving as an image to your desktop once a temporary passcode has been provided for Account Management access.


  1. My temporary passcode has expired

The temporary passcode is intended to provide full access to both Account Management and the trading platforms for a period of 2 days.  After 2 days, the temporary passcode may no longer be used to access the trading platforms but may be used to access Account Management for an additional period of 10 days.  The Account Management access, however, is limited solely for the purpose of printing or saving the on-line security card.   

If your window of access to Account Management using the temporary passcode remains, you may print or save the on-line security card through which full access to both Account Management and the trading platforms is provided for a period of 21 days. If you are unable to log into Account Management, you will need to contact your regional Customer Service center for assistance.


  1. My on-line security card has expired

The on-line security card is intended to provide full access to both Account Management and the trading platforms for a period of 21 days. This time frame, while limited, is intended to provide sufficient opportunity for the account holder to either regain possession of a temporarily unavailable security device or request and receive a replacement device. 

If you are unable to log in using the on-line security card, you will need to contact your regional Customer Service center for assistance and to provide information as to the status of your permanent security device.



  1. I am able to log into Account Management with my temporary passcode but not the trading platform

If your window of access to Account Management using the temporary passcode remains, you may print or save the on-line security card through which full access to both Account Management and the trading platforms is provided for a period of 21 days. 

If you are unable to log into Account Management, you will need to contact your regional Customer Service center for assistance.


  1. I am in possession of my security device and wish to activate it.

To activate either a replacement device or one which was temporarily unavailable and which required issuance of a temporary passcode, you will need to log into Account Management and select the reactivate security device menu option.  Once reactivated, neither the temporary passcode nor on-line security card will remain operable.
