How to enable explorer context menu

I noticed that there is a rightclick context menu entry called “show/restore backups” (translated from german) in the windows explorer.
When I click it I get an error “Error while connecting to the server. Can’t access the file.” (also translated)

In the Web GUI I noticed that there is a setting called “Internet restore authentication key”. Maybe this has something to do with this.

Does anybody know how to enable this feature?

Everything else is working.

Thx.

Ahhh… I see… I had to enter the “Server URL” configuration field :stuck_out_tongue_winking_eye:
