5 DAYS AGO HBO channels STOPPED WORKING on TV with ERROR MESSAGE XRE-03059

I have HBO/HBO MAX in my account. 5 days ago HBO stopped working on my TV and I get a ERROR MESSAGE. However with one of the HBO channels  (551) TV jumps to HBO at 801 (HD) and that works. All other non-HBO channels are working.

I had a long conversation yesterday with a Live Agent and they wish to send a technician. Based on my knowledge and experience I believe this is not a problem at my location but a problem at the Comcast End. After escalating yesterday, Agent booked a tech to visit my home. Suddenly, last night HBO worked on my TV so I cancelled the tech visit. But this morning again I got same Error Message XRE-03059. Can this be resolved by a tech visit or as my suspicion is that it is a problem at the other end not at my home-END  because it is a problem ONLY with HBO CHANNELS? Any suggestions - I have already tried un-plug and re-plug and refresh?
