Hi Tim van den Oudenhoven , the connection availability can be checked in Trados Studio -> File -> Setup -> Servers -> Select the server -> Check availability. If the connection shows as available, I guess it worth trying removing the local connection information file (the file where the GS connection is stored locally): https://gateway.sdl.com/apex/communityknowledge?articleName=000014720 . Other than that I cannot think of any other reason why you might end up with this error message.

Thanks for your response, Alex.
Unfortunately, the authentication error remains (the server is available and removing that connection file didn't work either). I disabled firewalls to check if it might be blocked, but that doesn't seem to be it either. Strange indeed...

I think the issue started when I installed the SR2 update of Trados 2021.

Hello! 

I am sorry to be responding to a thread posted more than one year ago, but I came across the exact same problem today. I thought it may be worth consulting you. Were you able to resolve the issue? What was the problem after all? How did you solve it?

I already tried changing my password, restarting the software, updating the software, restarting the computer and nothing seems to work. I am really frustrated with this.

Thank you in advance for your help.

Hi,

The issue never really got resolved. Sometimes it worked again, sometimes it didn't, and the PMs and tech support couldn't really figure out why. Larger files were more of an issue ("large" being relative, like 2 MB or something).

[BTW - I was on mac with Trados running on Parallels, thinking this might be the issue (firewall-related), but the issue persisted when I tried it on a Windows machine]

This particular client switched from Groupshare projects to offline projects, also because the server connections were just too slow.

At least know that your customer PM can submit the files manually on their end. Not ideal, of course.

Cheers,

Tim
