Session Reliability

Citrix introduces the session reliability feature to all supported macOS platforms. Session reliability is enabled by default.

Session reliability reconnects ICA sessions seamlessly across network interruptions. For more information about session reliability, see Auto client reconnect and session reliability.


Policy settings in the DaaS Management Console

You can set the following policies for session reliability in the DaaS management console:

  • Session reliability connections

For more information, see Session reliability policy settings.


After setting the Session reliability connections, restart the VDA service and the HDX service, in this order, for your settings to take effect.


Unable to launch sessions after enabling session reliability through the policy setting.

To work around this issue, do the following:

  1. Ensure that the VDA service and HDX service are restarted, in this order, after you enable session reliability through the policy setting.
  2. On the VDA, run the following command to verify that the session reliability listener is running (using port 2598 as an example).

    netstat -an | grep 2598

    If there is no TCP listener on the session reliability port, enable the listener by running the following command.

    /opt/Citrix/VDA/bin/ctxreg update -k  "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\WinStations\cgp"   -v  "fEnableWinStation" -d "0x00000001"
