CM1000v2 connectivity state access denied
My internet went down this morning so I went through some basics first, power cycles, reseating cables, soft resets and cmd line resets. I took my nighthawk router out of the line and directly connected to my CM1000v2. The modem is showing solid upstream/downstream and online with activity so I checked the internal status. The connection is showing good but looking inside the cable connection I am showing connectivity state stuck on in progress and access denied for the comment. I am running Hardware Version 2.02 with firmware version V6.01.07 currently. I did go through a factory reset on the modem and swapped out my ethernet with a known good cable with no change. I have the event log before and after the reset attached. Looking for advice on this while I parse through the errors myself to see what I can do because cox is all shoulders on this.

It does look like my upstream is having a major power issue. Everything I am reading is that this should less than 37 dBmV. if this is my main concern what should I do about this because swapping modems likely would not resolve a power issue on the line. This has been running solidly for well over a year at this point so odd to see a power issue like this imo.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.html- I have linked the modem connection page already. Cox isn't getting communication to my modem so I had them re-provision the device. The modem is stating online with downstream/upstream solid and green so some form of communication is going to cox. I replaced the coax cables in use with no change. There is a convertor in my attic that is the only tossup as it just has an on light and may be the root cause of this whole disconnect.
