@user_ef1188 I am sorry to hear you are having the same issue. Have you had a chance to rule out the basics. Can you check the coax cable at the wall and the cable box, to make sure all connections are finger tight? If you connect using a splitter, please make sure the connections of the splitter as well. If you have an amplifier in the home, you will want to make sure it is plugged in and light is showing green. Lastly, don’t forget about the HDMI cord. These cords can come loose and cause reception issues. Please check it to make sure it has not been damaged. Please let us know if those steps helped your connection. 

We have the same issue. All day today, and nothing is working to fix it. Checked all connections, physically rebooted and did system refresh.  This one box is showing as not connected and unavailable. I couldn’t restart it from the website as it seems to be offline.
