AX86 Merlin 388.1 + AdGuard v0.107.23... Problem

[PxP]

Running:
AX86 Merlin 388.1 + AdGuard v0.107.23.

Worked almost without a flaw.
On average DNS stopped to work about every two weeks - but simple router reboot helped.
But today...
Suddenly internet stopped to work.
Router GUI = OK
AdGuard GUI = Upstream DNS servers, Bootstraps, Private reverse DNS servers, blocklist etc. etc + other settings = empty or defaulted...
I`ve Reinstalled/Reconfigurated/Updated AdGuard using amtm.

Tried to use Upstream server I`ve used many weeks before "crash":

CleanBrowsing Security Filter / DNSCrypt
sdns://AQMAAAAAAAAAEjE4NS4yMjguMTY4Ljk6ODQ0MyC8rDL61UNpFx8IMtYHUCfDIIzu8Ojpn5QY3HdgZdSPKRFjbGVhbmJyb3dzaW5nLm9yZw
but seems it`s down (Error: control/test_upstream_dns | Network Error)

Tried AdGuard / DNSCrypt:
sdns://AQMAAAAAAAAAETk0LjE0MC4xNC4xNDo1NDQzINErR_JS3PLCu_iZEIbq95zkSV2LFsigxDIuUsQhzIjIuZG5zY3J5cHQuZGVmYXVsdC5uczEuYWRndWFyZC5jb20
It works.

Currenlty using:
h3://dns.adguard-dns.com/dns-query

What happened???
I`ve understand that "maybe" Cleanbrowsing turned off DNSCrypt support today, but even if so - why all my AdGuard settings went "bye, bye" ???

Regards,

PxP

Why do you need DNSCrypt in first place? AdGuard Home has options for DoT, DoH and DoQ.
