Hi All,

I am having a problem when starting my CDT, it throws an error about authentification failure. We have DEV and QA in the same environment and they use the same Certificate Authority. The DEV CDT starts up fine but QA is giving problems. We have just upgraded from version to Everything was working before the upgrade. I have checked that the server and client certificates are still valid.

Please see below some of the errors I copied from my temp directory:




13:41:03.974 (07020) DBG> Starting authentication

13:41:10.584 (07020) DBG> SecureSession: Secure connection failed (can't connect to remote host) @SecureSession::SessionConnect

13:41:10.584 (07020) DBG> SecureSession: Lasterror: TcpConnection::ConnectSync, connect failed - 10061 (0x274d) No connection could be made because the target machine actively refused it.

13:41:10.584 (07020) ERR> Error 2 in SessionConnect(,21002,...), let's try other connection!

13:41:12.621 (07020) DBG> Let's stop rManager

13:41:10.584 (07020) ERR> Authentication start failed: -60

13:41:12.438 [exe.htm] [ERR] TerminalInitialize -> (-2147467259) / Terminal, certificate or authentication failure




Please let me know if you need more details.

Looking forward to your assistance 😊

Thanks and regards,

    Hi Lopedius,

    The error indicates there is problem with the certificate. Please follow

    the below steps to check certificates:

    1. In the Windows Start menu, select the Run option, type MMC and click

    the OK button.

    2. In the MMC window, select the File -> Add/Remove Snap-in...

    3. In the Add/Remove dialog, click the Add button

    4. Select Certificates -> Add

    5. In the Certificates dialog, select Computer account -> Next

    6. In the Select computer dialog, select Local computer# Finish

    7. Close Add Standalone Snap-in

    8. Close Add/Remove Sanp-in clickin OK

    9. In the left hand tree, navigate to Console Root - Certificates (Local

    Computer) - Personal - Certificates The new certificate should appear

    on the list on the right side. It can be identified by the Issued To

    column. The new certificate has the address that clients will use for

    connecting to the secured service.

    10. In the list, double-click the certificate

    11. In the General tab, there should be text: "You have a private key

    that corresponds to this certificate.". If this is missing the

    certificate cannot be used.

    12. In the "Certification Path" tab, all certificates should be OK.

    If everything allright with certificate, then check Terminal VU, exactly its logs.

    Have you upgraded server side components and CDT itself? Is this issue only on your machine?

    Hi Vanessa,

    Thanks for your response. I followed your instructions to add the Certificate snapshot into the MMC. After adding it, I could not see any of my personal certificates that I have installed on my browser. I had to Export them from my browser and import them into the MMC snapshot. However, after importing my certificates to the snapshot, they didn't have the text "You have a private key that corresponds to this certificate." but the browser one has the text. I also doubt this could be causing the problem because the DEV CDT is working perfectly. Really appreciate your effort.

    Hi Andrei,

    Thank you for your response. I have upgraded the server side components. I'm not sure what you mean when you say upgrade the CDT itself? Could you please clarify me.

    This issue is also affecting my colleagues. Appreciate all your help

    Thanks and regards,

    • Andrei,

      You are correct, errors are not good at all. I have checked that the WEB VU IP address under Web Clients is correctly entered (It is the TERMINAL VU's IP address).

      Problem 2. And for some strange reason, the administrator account is no longer working, I even tried loggin on without the password. My account has the limited administrator role so it's not able to view the "Administrators" link on the manage window.

    Hi All,

    I managed to sort out this problem. The problem was on the IA under the components for the Terminals VU. It was using the ETC instead of the Connections Server for connections.
