Reconnect issue mqtt

[1968-Larry]

Describe the bug Problem when network goes down // reconnecting to mqtt-server.

Relevant firmware information: ESP32, mqtt with ssl, version 2.1.2, HAN baud 2400 8e1, entso-e api disabled.

Additional context When mqtt-server is not responding for a while, the esp32 becomes unavailible. Needs power reset to come back online. Trying to reproduce without SSL with no success so far.

Most likely a memory leak when reconnecting with SSL, I will have a look when I got some time to spare

[1968-Larry]

Without SSL it seems stable, but changing port number from working mqtt-ssl to something random makes everything unstable. Ping request works but not web.

Tried latest version 2.1.7 connected to serial debug without HAN connected.

When do you get this error?

[1968-Larry]

First I connect to working mqtt-ssl, change port to something random. More stable I think if booted with wrong port.

Found out why this happens, will be fixed in next release.
