Ad Guard Home not working after last update

Hello, just upgrade my router AP 1300 to 3.217 and ad-guard-home is not working anymore. Any tips?

adguardhome works fine in my ap1300 3.217.

Can you restore factory Settings and then test?

Please let me know the result
Thank you

I can do it, but before I want to know if I can make a backup through LUCI like a stock openwrt firmware and just restore after
