Cause

Limitation of Controller in some environments.

Environment

The problem has been seen (rarely) in some Controller on Cloud environments.

Resolving The Problem

The affected ('bad') user should logoff their Windows session (running on the relevant Citrix server).
  • NOTE: This does not mean that the user should logoff from the Citrix website (for example Citrix Netscaler website). Instead, the user must perform the steps (below) which logs their Windows session off (from the Citrix server).
   
Afterwards, re-launch the Controller client.
   
Steps:

There are other methods of achieving a logoff from Citrix (see separate IBM Technote #1978164 for more examples).

  • Below is the simplest method for most circumstances:

1. IMPORTANT: Make sure that the Controller application (with the error message described above) is:

(a) visibly running on your screen

(b) and highlighted/selected/in-focus.

2. On your keyboard, tap the following keys simultaneously:     CTRL     F1

  • The following screen should appear:

3. Click 'Sign Out'

4. Inside the Citrix website, launch the Controller icon. This time it will work OK (no error).
