Losing HD local channels for past several weeks

I have been losing local channels in HD for the past several weeks (ABC, NBC, FOX, CBS), typically two at a time.  SD channels are still accessible.  When I try to tune to these channels, the screen displays amessage saying the system cannot connect at this time and displays an error code: XRE-03059.  I've tried to call (total waste of time; automated system restarted my X1 receiver remotely which I have done myself countless times).  I saw an earlier post with a response indicating a possible "frequency issue" and advised sending a chat message using "peer to peer" at the top of the page but I have no such icon at the top of my page to provide my service address.

NOTE:  my next door neighbor has been having the same issues.
