描述

if wallet server stops sending notifications for some reason, client should detect that and switch to another server

for example: if you send a tx and never receive a notification for it, but then you get a new block that contains an address notification for that tx, then you know the server is not sending you notifications

研究方向
Investigate the current notification mechanism in the lbry sdk, likely involving WebSocket or similar. Look at files related to wallet server communication, such as 'lbry/wallet/server.py' or 'lbry/extras/daemon.py'. The issue suggests a timeout detection: if a transaction notification is not received but later a block notification contains it, the server is faulty. A solution could involve a heartbeat or a timeout on expected notifications. Examine existing tests for notification handling to understand the flow.
