EcoStruxure Building Operation
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
- Workstation is connected via HTTPS but there is no valid certificate
Resolution
Solution 1
If using 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
Workstation is connected via HTTPS but there is no valid certificate. Ensure that certificates are installed and trusted on the workstation/server so that no certificate warnings are received or use HTTP to connect to the server.
Solution 6
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.
