Cannot clone repositories (returns empty folder)

[Pierpaolo D'Aimmo (MIS)]

Bitbucket server. We have repositories that we could clone in the past.

I can work on those repositories (pull/push), but if I clone them again in a new folder, clone would return an empty folder. 

So Bitbucket was working normally until few months ago, now for some unknown reason nobody in our company can clone anymore repositories (old or new ones).

Tried with 4 different accounts, one of which is administrator. Tried on Windows 10 and Mac OS.

Tried on different repositories and projects.

Tried from command line and from Sourcetree.

Clone fetches data, and at the end I have just an empty folder, not even a .git/ folder, just nothing.
