Firmware Status -- No address record found for the selected mirror

[opn.spl]

Hello everyone!
I have the following problems after the last update: "Firmware Status --
 No address record found for the selected mirror" and my AdGuardHome is off.

The problem with the update error was quickly solved with DNS 8.8.8.8 (Setting→ General). But I can't get the AdGuardHome to work.

Maybe someone has the same problem since the last firmware update.
