blocking may work temporarily

I am using this regex now ^r+[0-9]+.sn-[a-z0-9-]+.googlevideo.com$. when an ads is loading then goes here rr1---sn-p5qddn7z..googlevideo.com

I had stop the firefox the auto-running the videos so I can look easier in the logs. regex blacklisted rr1---sn-p5qddn7z.googlevideo.com is 0.0.0.0

Omada router > set proxy DNS > points to PiHole, using Custom DNS > DNS server Chain is long I know but is set for other purposes.
