Activating modem, error 403

I just picked up my Cox modem a couple of hours ago, set it all up and followed all of the instructions correctly, but when I connect to my WiFi it gives me a page saying that I need to activate my modem. So I click the button that says activate, and it gives me an Error 403 Forbidden page. It says the following: "The server understood the request but refuses to authorize it." I don't know what to do here, I've called the support line multiple times but can't get through, and talked to a "live person" through the customer support and "he" tried to help me fix it, and accomplished nothing. I'm truly lost on what to do, if anyone could help it would be greatly appreciated.

    What is "...my WiFi...?"  Is it the Cox page to manage your network or are your referring to your actual wireless LAN?

    Do all the lights on the front of your modem illuminate steady?

    I should have mentioned also receiving a 403 error this morning logging into the Forum.  It was the first I received one and quite detailed.  I just refreshed the page and it eventually took.

    This isn't the same problem but perhaps a hint to something within the authentication process.

    I have run into the same exact problem ... the support rep told me to try different coxial lines in my home, but I still have the exact same issue.

    Were you able to get support or fix the issue?

    I am having the same exact issue. I am a new customer and haven't been able to get it activated. I've tried all the other connections in the home. I don't want to have a tech out because of covid-19.

    I’m also having this same issue. A new user using a Motorola MB7621 cable modem connecting directly to computer with ethernet cable. Lights on modem don’t reflect any errors. Cox rep is able to reset modem from there end and they’re not seeing any issues, but any browser use results in a Cox web page saying the modem needs to be activated and clicking the Activate Modem button results in the same 403 errors that the others reported.
