Error message when using Trados Studio 2022 Professional (17.0.6.14902) remotely over VPN Tunnel

Michael Bailey

How can I solve the error "Der Remoteserver hat einen Fehler zurückgegeben: (407) Proxyauthentifizierung erforderlich." in Trados Studio 2022 Professional - 17.0.6.14902 when working remotely? 

For the last couple of days when working remotely, Trados Studio 2022 Professional - 17.0.6.14902 has been crashing regularly. The same files worked in the office without problem.

Having tried a "divide and conquer" approach to establish whether the problem was in the file to be translated, (as crashes were frequently in the same place of the file) I have managed to get another file to work properly. However, it often takes over a minute for the "not responding" in the header to disappear, when moving to the next segment.

The issue from the log below seems to be related to LanguageCloudService - which we don't use. 

ERROR [2023-09-20 09:09:33,119] Sdl.BestMatchServiceStudioIntegration.Common.LanguageCloudService - Fehler beim Senden der Anforderung.
System.Net.Http.HttpRequestException: Fehler beim Senden der Anforderung. ---> System.Net.WebException: Der Remoteserver hat einen Fehler zurückgegeben: (407) Proxyauthentifizierung erforderlich.

I have tried also to deactivate system plugins relating to MT providers to see if that helps, but all the system plug-ins are greyed out.

Any help gratefully received, thanks in advance!

    Hello,

    Based on the error message you're receiving and the context provided, it seems like the issue is related to your proxy settings. Here's how you can resolve this:

    Step 1: Navigate to the following location on your computer: C:\Program Files (x86)\Trados\Trados Studio\Studio17 for Trados Studio 2022.

    Step 2: Find the file named 'SDLTradosStudio.exe.config' and open it in a text editor.

    Step 3: Look for the <system.net> element in the file.

    Step 4: Add the <defaultProxy> tag in the <system.net> element. The <defaultProxy> tag should have the attribute 'useDefaultCredentials' set to 'true'.

    So, your <system.net> element should look like this after the changes:

    <system.net>

       <settings>

           <servicePointManager expect100Continue="false" />

       </settings>

       <defaultProxy useDefaultCredentials="true">

       </defaultProxy>

    </system.net>

    Step 5: Save and close the file.

    This should resolve the proxy authentication issue you're experiencing when using Trados Studio 2022 Professional remotely over a VPN tunnel. If the problem persists, you might want to check your VPN settings or contact your network administrator for further assistance.

    I hope this helps! If you have any other questions or need further clarification, feel free to ask.

    Best regards,
