ADGuardHome Failure after upgrade to 4.6.8 on BRUME2

Technical Support for Routers

Hi,
I upgraded the firmware of my BRUME2 to ver.4.6.8 but upon reboot I could not access the ADGuard Home configuration page and I could no longer go to the internet. I restarted the router several times but always with the same problem, only by disabling ADGuard was I able to access the Internet. By enabling ADGuard I find these error messages in the router log

Can anyone help me?

Thanks

Seems like you upgraded AdGuard Home before and now you are running an older version again. (This is by design because the AGH bundled with the firmware is way older)
Disable AGH and update it again using [Script] Update AdGuard Home

Next time when you upgrade firmware and keep backup only config.yaml in Adguard home. Then delete config.yaml and try upgrade Adguard home from @admon 's script. Finally put back Adguard config.yaml for restore your saved setting Adguard home.

How to get that file? Try use WinSPC for windows os

Overall reason config.yaml does have one line with number scheme version. If not match that upgraded firmware with old Adguard home base version then not working everything.
