[horde] Check for newer versions - failed

[Andreas Mauser]

Hi,

just found, that the button "check for newer versions" returns an error message: Der Server konnte nicht erreicht werden, bitte versuchen Sie es später noch einmal. (Server cannot be reached, pls try again later).

But the VM where Horde6 resides can ping the outside and can apt install anything, so I wonder if you may have seen that behaviour before?

Best regards,
Andreas
