Double NAT Detected on Xbox Series X

I recently purchased a new Cable modem router to replace my isp provided equipment. I set up the router and all of my other equipment that is linked with this new router works well, except my Xbox series x is giving me the Double NAT Detected error which was my original issue and why I purchased this in the first place. I have tried port forwarding and a few other fixes found online but I am at a loss. Any help would be greatly appreciated. Thanks.

    What is "all your other equipment"?

    A details listing of your setup (modem/router/switches/etc) is key in helping you

      By other equipment I just meant everything running of the router. I have a cell phone booster that is plugged in via Ethernet cable. And my Xbox is also plugged via Ethernet. Other than that I have quite a few different devices running off the router wirelessly with no issues. As far as any problems I have connection wise is just my Xbox series x console is showing a double NAT Detected. As far as my internet connections I have the AC1900 cable modem router model C7000v2 plugged into power with the cable coming straight out of the wall with no splitters or anything going straight to the modem router I listed.
