How do I reset my cable boxes without having to call in when the connection reset tool says my Whole Home DVR boxes are not eligible?

I have had my whole home DVR maybe a year and every month I personally have to reset my boxes. If I don't, then after about 5 weeks I start missing DVR recordings because it says the recorder isn't available while it is recording only a single show. My most recent miss was the epic season finale of flash that I ended up having to wait over a week to watch before it was actually put on On-Demand, of which of course mostly was spoiled to me by media and other people who got to see it because their DVR system doesn't ***. I can't just unplug it because my home theatre system is built in and not easily accessible. When I call to talk to someone they say to use the online tool but it doesn't work for me because it says my equipment is not eligible for a cable box refresh. My only option is to call and go through all the phone prompts to do it and that is a pain. It is so frustrating to have a new system and be told that I should be able to use the online reset tool but not be told why it does not work for me. Why won't it work? How can I get it fixed? The last time I spoke to Cox about this was 3 months ago and I was told they were sending it to their internet website people saying it was an issue with the website. But at the same time I went over to a friend and had him do it for his stuff and it worked perfect. Since then I have not got any information from Cox and it is just very discouraging. Anyone else have this problem?
