SDL Studio 2019 - Issue working with Multiterm

I have an SDL Studio 2019 license installed in my laptotp and the different components of it are working properly except for Multiterm.

In fact, when  opening  Multiterm I am prompted wiith the follwoing messsage: "A connection to SDL MultiTerm Server unknown could not be established.Please check your connection settings."

How do I manage to solve this issue?

In fact, I have an urgent job to complete and am not able to work with Terminology databases.
