PiHole fails to provide internet connection after ASUS router update

Please follow the below template, it will help us to help

Expected Behaviour:

Updated firmware on ASUS GT-AX11000. Have had PiHole running for past 6 months flawlessly in the past.

Actual Behaviour:

After firmware update, no connection to the internet while pihole is listed DNS server in router. Can set DNS server to 8.8.8.8 and everything works fine again. Setting it back to pihole causes no internet to be available again.

I would revert your firmware back to the previous version.
