Steps to reproduce
- Disconnect the ethernet connection for an hour or so
- Reconnect
- MQTT is writing data but stops after a few seconds
If you disconnect ethernet for a short period of time, lets say, 1 or 2 Minutes the problem does not occur. But longer disconnection time leads to problems.
Yes but not much.
