Article Summary

Liquit Workspace environment variables not updated in real-time

Liquit Workspace will use environment variables and their value from the start of the Universal Agent (Liquit Workspace Service) and will not update the values while running. If filters, actions, and processes use environment variables Liquit Workspace will use the startup values and not the current values. Only environment variables and the value changed with the actions “Set environment variable” or “Unset environment variable” will be updated. New environment variables that did not exist during the start will be picked up.

Pin to taskbar doesn't work on Windows 10 Version 1903 and later.

Liquit Workspace affected versions: 3.0 and later

In older versions of Windows 10, it is possible to pin applications to the taskbar. Due to changes in Windows 10 Version 1903 and later, this functionality is unavailable for the affected versions of Liquit Workspace. There is no ETA on when or if this issue will be fixed.

Liquit Workspace Agent doesn't work after updating to version 20H2 of Windows 10.

Liquit Workspace affected versions: 3.6 Build 2230 and earlier

Certificates may not be present after updating to version 20H2 of Windows 10. For more information about this issue, see Microsoft documentation.

Workaround:

  • Reinstalling the Liquit Workspace Agent will fix the issue.
  • Install Liquit Workspace Agent 3.6 Build 2237 or later before upgrading to Windows 10 version 20H2.

When viewing the dashboards in the Launcher an error is shown

When you view the dashboards in the Launcher, you are prompted to upgrade to a different browser.

Workaround:
For the best experience, we advise you to use a web browser to access the dashboards.

FaultException Invalid user session

Possible cause: A session that is stuck in the database.
A session object may become stuck, which could prevent a user from logging in.

Workaround:

This workaround will delete all user sessions and all the users will be logged out forcibly.

  • In Liquit Workspace, navigate to Automation > Scheduled Tasks and open the Clean Sessions task.
  • Navigate to the Settings screen. Set the number of hours to 0 (zero).
  • Navigate to the Schedule screen. Delete the default interval of 5 minutes.
  • Run the task. You will be logged out while the task runs because also the current user session is being deleted.
  • Log back into Liquit Workspace and navigate back to the Clean Sessions task.
  • Navigate to the Settings screen. Set the number of hours back to 8, the default value.
  • Navigate to the Schedule screen. Add an interval of 5 minutes. This is the default value.

"An unexpected database error has occurred" during login

Possible cause: The Liquit Workspace Server is unable to reach the database.
It is important that all Liquit Workspace Servers have a reliable network connection to the database to perform correctly.

Workaround

  • Check the connectionString parameter in the Server.json file.
  • Ping the address specified in the connectionString parameter with the name "Data Source".
  • Check the server log files for database errors.

Possible cause: The event table has reached the maximum amount of records supported.
Liquit Workspace affected versions: 3.0 and later

Especially in older versions with the Liquit Server, it is possible that the event table in the database has reached the maximum amount of records supported. This can happen if the task for cleaning events hasn't run or is configured to retain too many days of events. We recommend for large deployments to not set the retention period for more than 30 days.

Workaround

This workaround will delete all existing events.

  • Log into the Liquit Workspace database using an SQL client, like Microsoft SQL Server Management Studio.
  • Execute the following SQL query on the database:
TRUNCATE TABLE [Events];

NTLM/Kerberos doesn't work

Possible cause: The integration with Active Directory will use the Identity Source name as a realm.
The realm name for NTLM/Kerberos must match the Active Directory NetBIOS name before single sign-on could work.

Workaround: Make sure the Identity Source for Active Directory name is matching the NetBIOS name of Active Directory.


Possible cause: Internet Explorer will only engage an NTLM/Kerberos handshake if the visited site is listed in the trusted zone list.

Workaround: Make sure the Liquit Workspace Zone is listed in the trusted zone list of Internet Explorer.


Possible cause: The Kerberos token exceeds the allowed size.
Note: Liquit Workspace makes use of the HTTP.sys that is provided with Windows.

Workaround: Follow the steps provided in the Microsoft documentation.

Firefox is unable to communicate with the Liquit Agent, Cross-Origin-request blocked

Possible cause: Firefox doesn't trust the certificate of the Liquit Workspace Agent.
Firefox doesn't use the Windows Certificate Store for validating certificates. This could cause Firefox to not trust the Liquit Workspace Agent certificate.

Workaround 1: Import the Liquit Workspace Agent certificate in Firefox.

The location of the certificate on Windows is:

  • Workspace Agent: C:\Program Files (x86)\Liquit Workspace\Agent\Agent.pfx for the or
  • Universal Agent C:\Program Files\Liquit Universal Agent\Resources\Agent.pfx.

The password for this file is "agent" without quotes. It is also available in the Windows Certificate Store under the friendly name "LWA".

Workaround 2: Create the following registry key HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox\Certificates\ImportEnterpriseRoots with DWORD value of "1" to let Firefox automatically import the trusted certificate roots from the Windows Certificate Store. This is supported by Firefox starting version 60 and later.

Edge can’t communicate with the agent

This issue only affects Microsoft Edge Legacy.

Possible cause: Microsoft Edge does not communicate with the Liquit Workspace Agent, because localhost loopback is not allowed.

Workaround: Enable local host loopback.

  1. Open Microsoft Edge
  2. Navigate to about:flags
  3. Enable localhost loopback

allow-local-loopback

Server installation ends in "Installation ended prematurely"

This generally indicates that there was an issue while trying to upgrade the database schema.
To assist us in finding the issue where this problem occurred, we need the debug logging of the installation.

Workaround:
After restoring the database, re-install the Liquit Workspace Server with the following command-line prompt:

msiexec /i Liquit-Workspace-Server.msi /l*v setup.log

Send the resulting setup.log file to the Liquit support department, so we can investigate what is causing the installation to end prematurely.

UserHost not found for session

Possible cause: The UserHost is not running.

Workaround: Make sure the UserHost is running correctly and is not elevated.


Possible cause: Firewall software intercepts all localhost connections.

symptoms:

  • The specified session is 0 (system)
  • In the agent debug log files the origin process is 'swi_fc' (Sophos endpoint security)

Workaround: Make sure that the firewall software doesn't intercept lost host connections. For Sophos endpoint security, you can add a global exclusion for IP address 127.0.0.1:

Citrix Receiver doesn't start automatically from Chrome

Possible cause: Starting with Google Chrome version 77 and Microsoft Edge (Chromium) it is possible that you no longer see the “always open these types of links in the associated app” prompt when an external app is launched through a link in Chrome or Edge.

Google Chrome workaround: Set the following registry value for allow-listing the Citrix Receiver, Citrix Workspace and the VMware Horizon client:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\URLWhitelist]
"1"="receiver://*"
"2"="vmware-view://*"

Microsoft Edge workaround: Set the following registry value for allow-listing the Citrix Receiver, Citrix Workspace and the VMware Horizon client:

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\URLAllowlist]
"1"="receiver://*"
"2"="vmware-view://*"
