‘You were disconnected by another user. (521)’

Error description

Another user logged into the VM using the same username. Control of the VM is automatically assigned to the most recent RDP user to sign into the VM.

Resolution

To regain control of the session, refresh your browser and log back into the guest operating system session. If you are using multiple browser tabs to connect to the same VM, close the extra sessions.

Advanced troubleshooting

If multiple users need to share an over-the-shoulder VM session:

  1. Switch the browser client connection type to Standard.

    1. In the browser client toolbar, click yes.
    2. Select the Standard (no audio) connection type.
