Timed out while trying to find a valid host address and port

Error message

Timed out while trying to find a valid host address and port

What it means

Timeout guard in getLatestAdbDaemon(): the CountDownLatch waiting on mDNS discovery (TCP-connect and, on P+, TLS-connect services) expired before any service resolved a host address and port, or the resolved values were null. Wireless debugging may be off, the device on a different subnet, or mDNS packets blocked — no valid endpoint was found in time.

Solutions

1. Increase the discovery timeout and retry
2. Have the user toggle Wireless debugging off/on to re-announce mDNS services
3. Ensure multicast/mDNS traffic is allowed on the network
4. Fall back to manual entry of the pairing host and port

When it happens

Trigger: Thrown at app/src/main/java/io/github/muntashirakon/AppManager/adb/AdbUtils.java:88 when the library encounters an invalid state.

Common situations: See trigger scenarios.
