MQTT never connects if ESP32 not connected to internet about espresense

[DTTerastar]

It's stuck trying to sync time:

{
    configTime(0, 0, "pool.ntp.org", "time.nist.gov"); // UTC

    time_t now = time(nullptr);
    while (now < 8 * 3600 * 2)
    {
        yield();
        delay(500);
        now = time(nullptr);
    }

    struct tm timeinfo;
    gmtime_r(&now, &timeinfo);
    log_i(F("NTP synced, current time: %s"), asctime(&timeinfo));
}

Do you restrict it from the internet by chance?

I think I can actually remove this. I ended up not actually needing the time.

I sure do, my IOT subnet for ESPs does not get internet access - that would certainly explain it. My MQTT server also happens to be my local SNTP server - could NTP settings be parameterized / added to the captive portal?

I would like to control the NTP sever too, can you take it from DHCP, please?

I didn't actually end up using the time for anything so I've just disabled it for now:

https://github.com/ESPresense/ESPresense/releases/tag/v1.3.1

Please try that.

Can confirm - v1.3.1 connects to MQTT and detects devices without internet access.
