eero tried to access x1.c.lencr.org

hi all

I recently activated the free verizon home network protection on my quantum gateway router. I got messages yesterday that one of the xboxes in the house was trying to access x1.c.lenr.org. today I am getting the message that eero is doing so. I have not allowed it of course. I was curious if there was a way to narrow down which device is doing it - I wonder which xbox it is and if anything else is doing it. I figure it is a browser redirect.

any help would be appreciated, I figure since it is going thru the eeros maybe we can figure it out

current set up:

quantum gateway -> eero mesh as the wifi but in bridge mode. 

thank you!

(ps I figured a post here may be more fruitful than on the vz forums but of course  I can ask there.)
