Adding a server-based termbase in Trados Studio

Hello!

I'm trying to add a termbase I created in Multiterm to an open Project in Trados Studio, but when I click on the "Servers" button in "Select Termbases", all it tells me is that https://groupshare.eurocom.at/ is not available... How can I link my Multiterm termbase to my translation in Trados?

Many thanks
