Random error in MQTTClient::loop() function about arduino-mqtt HOT 2 OPEN

Thanks for the report, the included snippet made me think and I found an integer casting issue:

auto available = (size_t)this->netClient->available();

The available method actually returns an int, so my feeling is that your network layer may return a negative number to indicate an error code. When casting it to size_t the number becomes very large due to "Two's Complement".

I fixed the issue and released a new version. Let me know if it helps.

Hi @256dpi
Apply the mentioned changes and uncomment that part of the code in my firmware.
I've been testing this for a few days and for now I don't have any disconnection events, I think the problem is solved.

Thank you so much
