## Bug fixes

* Fixed a bug that caused Action Center to fail loading, after upgrading to newer versions, using the `Load Balancer URL`, only if the following steps are made before the upgrade process:

  :::important
  Manually add the correct value of the `Action_Center_URL` key in the registry at **Path** `Computer\)\)HKEY_LOCAL_MACHINE\)\)SOFTWARE\)\)WOW6432Node\)\)UiPath\)\)UiPath Action Center`.

  To find the correct value of the `Action_Center_URL` from the `env.json` file:

  * Navigate to the **Installation Folder**.
  * Go to the `ActionCenter/Actions/environments/env.json` file path.
  * From the `PostLogoutRedirectUri` key, retrieve the correct **Action_Center_URL**.

  The format for the `PostLogoutRedirectUri` is `"Action Center URL"/actions`. For example, if the `PostLogoutRedirectUri` is `https://action-center.loadbalancer.uipath.com:447/actions`, then the corresponding **Action Center URL** is `https://action-center.loadbalancer.uipath.com:447`.

  If the correct value of the `Action_Center_URL` is not provided before starting the upgrade process, then the initial bug reappears and you will need to manually update the `env.json` file. For step-by-step instructions on how to update the `env.json` file, check the last row from [Action Center installation issues](https://docs.uipath.com/action-center/standalone/2021.10/user-guide/action-center-installation-troubleshooting).
