Messages not sent/received for several minutes after switching networks #1634

Steps to reproduce:

  1. Connect to wifi network
  2. Run Quiet, send a message, confirm it was received quickly
  3. Switch wifi networks (or to mobile data)
  4. Send another message immediately

Expected: it is always received immediately or after a short delay (a few seconds for Tor to connect) Actual: it is received after several minutes (6 in one test, ~20 in another test)

Why is this taking so long and what can we do about it?

In a test on desktop, the logs were silent when I switched networks: no apparent problems but also no sign that it was aware of a problem. When messages were received, I looked back in the logs and there some libp2p PEER_DISCONNECTED events that set in motion new connections. I think this means libp2p + websockets + Tor takes a lot of time to learn it was disconnected, but we should confirm this.

I'm putting this in "Next Sprint" because leaving it unfixed will cause apparent instability and could create issues in the future.
