Reconnect is failing

[LarryKanionga]

We are getting a client disconnect message immediately after the connection was successfully setup, this happens when the server is down and then comes to active

According to the traces, while the server is down, one connection channel is keep opened on port 8883.

When the server is restarted and it tries to reconnect (using mqttclient.connect), the connection is established and immediately the connection is closed after few milliseconds. This is also happening, when we call the disconnect message after the device notices that the server is down.

Any ideas? Thank you for the help.

Hi, guys. sorry for this bug. It may be caused by the original Timer mechanism.

@jmiltner has fixed the timer mechanism in the #246.

Could you check the auto-reconnect mechanism in the 1.2.0 version? I think it has been fixed!

@keshavx11 Can you provide the example code to help me to reproduce it? Thanks!

How do you test the re-connect mechanism?

[keshavx11]

Please ignore. The issue i have is because of #259
Not related to this
