I think I'm ussing the latest one
but as you said I don't think it will fix my issue though.
But looking at the examples I found that they have a connect function which then can be used to reconnect whenever needed not constantly like it happens now,
But not sure how I could integrate that functionality in this sketch though, as I'm not that experienced with programming :/
To you think it will be possible?
/*
Reconnecting MQTT example - non-blocking
This sketch demonstrates how to keep the client connected
using a non-blocking reconnect function. If the client loses
its connection, it attempts to reconnect every 5 seconds
without blocking the main loop.
