Error ""A connection to MultiTerm Server unknown could not be established. Please check your connection settings."

Hi,

I am trying to open an existing termbase and I get this message "A connection to MultiTerm Server unknown could not be established. Please check your connection settings.".

Here are the details:

I then try to create a NEW termbase, to check if the old ones are corrupted, and I get the message "Object reference not set to an instance of an object".
The app was working perfectly a few days ago. I have tried all usual method (repair, uninstall, rename folder) but nothing worked.
Could you please help?
Thank you

  • Hi Elena

    Frome the first part of the error message, it looks like you are trying to connect to Trados GroupShare - I think (someone fmo RWS may say I'm wrong!) that's the only place where "MultiTerm Server" is used.  Just to confirm that, do you see the Administrator control at the bottom left of the MultiTerm window:

    Screenshot showing the MultiTerm window with the Administrator tab highlighted under Termbase Management.

    That only appears if you have configured to connect a GroupShare server.  Then, of course, to add a Termbase, you use this button

    Screenshot showing the AddCreate button highlighted in the toolbar of the MultiTerm interface.

    rather than this one:

    Screenshot showing the Create Termbase option highlighted in the toolbar of the MultiTerm interface.

    If you have GroupShare, but can't see the Administrator tab, go to File/Setup/Servers and edit or add your server connection.  Of course, in GroupShare, you need to confirm that you have the rights to create a Termbase.

    Of course, if you don't have GroupShare, none of this is relevant!  In that case, try this article:

    A connection to SDL MultiTerm Server unknown could not be established. Please check your connection settings - 3. MultiTerm - Trados Studio - RWS Community

    It seemed to give a solutions for that case.

    Hope that helps - Rob

  • Hi Robert,

    Thank you for your answer and time.

    I don't have a GroupShare server. I also tried the instructions of the link provided, but unfortunately I still have the same issue.

    Actually, I run to the following error:
