On Demand not working persistent error code CL-17 (PR150BNM / RNG150N box) Ticket # CR001509057

Hello -

Tried to resolve this twice previously via Xfinity Assistant online chat but no joy, so I'm reaching out here.

Problem: the 'On Demand' function is not working (and hasn't been for quite a while), with a dialog box and error CL-17 when attempted.  The 'Search TV & On Demand' function also does not work, with different dialog box and error MOGSCNA.  These functions have worked in the past with this box & TV.

Numerous unplugging/re-plugging cycles with the box have been done, along with several "I just sent a reset/refresh signal" and a couple of subsequent "the signal I sent will fix the problem but it will take 30 minutes to re-synchronize" tries by the online help chat people.  The box did receive reset signals as evidenced by the Channel Guide reverting to "To be announced" for all channel content, but the On Demand & Search problems remain.

I have reviewed the Diagnostic Menu pages available within the PR150BNM/RNG150N set-top box with some of the following info:  The Diagnostics Dashboard indicates NO IP ADDRESS and NO IPPV ENABLED in brown color, with all other fields being green/GOOD or N/A (for DVR and HDD which are not present in this box).  My understanding is the box should request an IP address any time it is lost, and when the On Demand function has been working in the past there was always an IP address present.

I'll include a few (hopefully) pertinent screen shots in case some serious tech type folks happen to see this post and can offer some insight...
