If you don't use a static address for your box it will take from DHCP another address in your local net every time you reboot and i think when it back from standbay too. Use the Dream Box Control Center (DCC), make a search and use the box address found for connecting the server. You can use a static address when you config the WiFi or the wired connection of your box and then use it always in TV-server.
And by the way what is another box, your second box or a neighbor using your net ? Don't give the name to confuse you. My box is recognised as DM800SE and when the address is correct the server conect it.

Hi,

Please post pictures of your Enigma-TV settings.
Then show us how you connect to your DM800 WebIF.
I would like to see the IP in the web browser.

Thanks,
