Custom client upstream DNS cache configuration not working properly

[MiKing233]

Prerequisites

• I have checked the Wiki and Discussions and found no answer

• I have searched other issues and found no duplicates

• I want to report a bug and not ask a question or ask for help

• I have set up AdGuard Home correctly and configured clients to use it. (Use the Discussions for help with installing and configuring clients.)

Platform (OS and CPU architecture)

Linux, ARM64

Installation

Custom package (OpenWrt, HomeAssistant, etc; please mention in the description)

Setup

On a router, DHCP is handled by the router

AdGuard Home version

v0.107.52

Action

在ADGH的web管理界面頂部的"Settings-Client settings"中, 點擊"Add Client", 設定名稱, 並使用IP地址Identifier辨識該客戶端, 在"Upstream DNS servers"標籤頁, 設定一個與全局上游DNS不一樣的DNS伺服器, 並在底部勾選"Enable DNS caching for this client's custom upstream configuration", 并設定"DNS cache size", 例如134217728bytes

Expected result

此時, 該客戶端的DNS請求應使用單獨設定的DNS上游伺服器, 并且存在DNS緩存

Actual result

但實際結果是, 自定義客戶端的DNS緩存并不生效, 通過檢查log發現, 每一次請求都會從上游DNS伺服器請求, 即使一直請求相同的域名, DNS緩存也不會正常工作, 檢查請求詳情, 其中也并未出現"Served from cache:✅"
