Ipn.State.Stopped,
Ipn.State.NoState -> {
TSLog.d(TAG, "Ignoring and dropping all health messages in state ${ipnState}")
dropAllWarnings()
return@collect
}
else -> {
TSLog.d(TAG, "Health updated: ${health?.Warnings?.keys?.sorted()}")
health?.Warnings?.let {
notifyHealthUpdated(it.values.mapNotNull { it }.toTypedArray())
}
}
