Bug: Memoization feature cause problem

When I'm working with the app, for example, I may forget to connect to the internet, shut down VPN, change proxy settings or something like that and want to recheck the domain again, but it's not possible because of the memoization feature, and the status "offline" is still displayed. In such circumstances, I can't try again unless I reopen the app.
Hence, the memoization feature is not helpful here.

查找與網路狀態檢查相關的 memoization 邏輯，可能位於處理連線的 service 或 utility 檔案中。找到在網路變更時被快取但未失效的 'offline' 狀態。透過在不重啟 app 的情況下模擬網路變更進行測試，驗證修復是否允許重新檢查網域。
