Wallet offline

[robbiehanson]

We've had several reports of wallets stuck in Offline mode:

We've gathered the following information from the reports:

• known to affect both iOS 15 & 16
• SwiftUI seems unaffected, but the underlying Kotlin layer seems to be frozen or otherwise non-responsive

Theory 1: Maybe the wallet isn't unlocked because:

• the read-from-keychain request never returned or
• the loadWallet function returns early (thinks wallet is already loaded)

Tests performed:

if the read-from-keychain request never returns, the UI is stuck in this state:

if the loadWallet function returns early, then the app crashes because of various assumptions, such as this one within the AppStatusButton:

let syncTxManager = Biz.syncManager!.syncTxManager

Theory 2: Maybe the database is corrupt

Test performed:

I tried purposefully corrupting the database file by overwriting it with random data. Result: the app crashed on launch

Another theory: an issue when serialising and/or uploading a payment to iCloud would deadlock the node bootstrap, leading to a responsive UI but a frozen node.

Maybe this helps: I've had connectivity issues with the lightning node today after a prolonged period of not using the app (about a month or so).

Setup:

• Tor: Disabled
• iCloud Backup: Enabled
• Randomized upload: Disabled

Ive tried the following to get it to connect:

• Switch from wifi to cellular: ❌
• Enable/Disable Tor: ❌
• Disable iCloud Backup: ✅

After successful connect, I've re-enabled iCloud backup again, quit the app and relaunched. It now connects to LN properly again. 🤷
