[d-a-v]

Too much time in this loop without yield() => WDT ?

    while (WiFi.status() != WL_CONNECTED && attempts < 60)
    {
        wifiLedUpdate();
        delay(500);
        Serial.print(".");
        attempts++;
    }

Is there a negative side of high delay in connection controls?

[d-a-v]

Is there a negative side of high delay in connection controls?

Yes

[asturcon3]

I really hate that String+=char loop in your callback function, with an unknown length... Just guessing

[abdosn]

    while (WiFi.status() != WL_CONNECTED && attempts < 60)
    {
        wifiLedUpdate();
        delay(500);
        Serial.print(".");
        attempts++;
    }

@d-a-v

does delay(500) have the effect of yield() ?

[d-a-v]

Yes yield() is called from inside delay()

[abdosn]

I agree with @asturcon3 about the use of String
Also casting c string to String class consumes memory and time
so try to use string.h functions instead of String class

in the callback function
I recall that either topic or message could have some garbage at the end instead of null character

Also in void reconnect() function
Add delay() or yield() inside while (!client.connected()) loop
