Environment

• Building Operation Workstation
• Building Operation Automation Server Premium

Cause

A second instance of the workstation is running on the same computer

The firewall is blocking the connection.

The password was recently changed during the same session

Resolution

Solution 1

If you use Remote Desktop (RDP) to access the SBO/EBO ES remotely, a second instance of the workstation could be initiated.

Close the workstation on both the remote connection and at the SBO/EBO ES.

Then open the workstation either at the SBO/EBO ES or via remote connection, not both.

Solution 2

Check if the firewall has been enabled while logged in to the SBO/EBO ES or AS, and disable the firewall

Here is an example for McAfee

Solution 3

Make sure the network information (such as gateway) for the PC is entered correctly.

Solution 4

If you just changed the password of the logged in user, log out and in again

Solution 5

Update the Certificate Revocation List as described in First time a TGML graphic is opened after logging in it takes a long time for the graphic to load.
