java - Android Firebase - 写入数据时持续超时

Question

我正在尝试将数据存储在实时 Firebase 数据库中。然而，即使是文档中最简单的示例也不起作用。

DatabaseReference myRef = database.getReference("message");
myRef.setValue("Hello, World!");

我启用了调试日志，并且注意到尝试连接到 Firebase 时本质上存在永久超时和重试机制。

D/Connection: conn_1 - Opening a connection
D/WebSocket: ws_1 - timed out on connect
D/WebSocket: ws_1 - closed
    ws_1 - closing itself
D/Connection: conn_1 - Realtime connection failed
D/Connection: conn_1 - closing realtime connection
D/PersistentConnection: pc_0 - Got on disconnect due to OTHER
D/PersistentConnection: pc_0 - Scheduling connection attempt
D/ConnectionRetryHelper: Scheduling retry in 964ms
D/PersistentConnection: pc_0 - Trying to fetch auth token
D/PersistentConnection: pc_0 - Successfully fetched token, opening connection
D/Connection: conn_2 - Opening a connection
D/WebSocket: ws_2 - timed out on connect

它会永远持续下去，数据库表当然永远不会更新。我能够正常执行读取操作。什么会导致这种情况？我使用的是普通 WiFi。我不支持任何类型的代理或 VPN。

看来是网络问题。我连接到了 HotSpot 网络，问题就解决了。
