Problem-pushing-forms-and-submissions-to-central-using-Briefcase

Hi, all.
I'm trying to push forms and submissions to Central using Briefcase v1.17;
after typing the "Push" button, the only thing I saw during, about one hour is "start pushing forms and submissions" and nothing else happens: no progress displayed, no forms and/or submissions pushed to my central.
Thanks in advance for any help.
Best,

Upgrade to Briefcase v1.18 if you need Central support.

Also, read https://docs.getodk.org/central-briefcase/

Thank you so much, @yanokwa .
Best regards.
