QNAP HS210 can not be connected

[Yazsan55]

Hi,

I have had difficulty to open Minimserver on my QNAP HS210 for a while.
I had not had changed anything but it started no-show.

I tried to open configuration page without success.
So I decided to reinstall Minim manually.

I did that and is installed but configuration page refuse to connect.

What is going on?

Many thanks for your help.
