Xfinity XB6-A WPS button blinks red three times when pressed

Hi Everyone, I am having a weird time with my Xfi Router. I was trying to use WPS (And yes I know its unsecure) to connect an xfinity flex box to my network. I pressed the button on the flex box and then the WPS button on the Xfi router, but I got a red light that was blinking three times. I was wondering if there's a way to troubleshoot the blinking light and fix the WPS issue.

I do want to add I logged into the router, and saw that WPS was enabled
