Server based multiterm issues

Good afternoon, dear Trados team!

We are encountering the following errors while trying to open a termbase after creating and importing it into our Groupshare server.
We have tried creating it as an existing termbase, from a .xdt file and even from scratch.
Also, we followed this Trados tutorial: How do I upload a file-based termbase (.SDLTB) to a GroupShare server?

The log error is the following:
