[Bug] Auto-Reconnect does not handle configuration change

Open SpeckiJ opened this issue 5 months ago • 1 comments

What did I do

  1. Try to connect to a broker with default settings but invalid Path (e.g. connecting to wss://broker.emqx.io:8084/mqtt_invalid_path.

  2. Notice that the Path is wrong, open configuration and fix the path (/mqtt_invalid_path --> /mqtt).

  3. Close configuration and start a new connection with the new configuration

What happened

The client successfully connects after fixing the configuration. But I receive Alerts about Reconnecting every couple of seconds. When looking at the Network-Tab in the Browser console it shows that it still tries to reconnect with the old invalid configuration, although i have changed them already.

The only workaround i have found so far to get rid of the background-reconnects is to refresh the page (via F5 or Ctrl+R in the Desktop Client).

Expected

When changing the configuration of a client all auto-reconnection attempts for this client should be cancelled. After I have changed the configuration the old configuration should not be used anymore.

Environment

More detail

This is probably a duplicate to https://github.com/emqx/MQTTX/issues/1680 that was unfortunately closed due to inactivity.
