Time Sync error: NTP server not reachable

[piter1235301]

Hello,
I've tried upload code, but I had a few issue.

The First was undefined reference to sntp_get_timezone but I set set IwIPVariant to 1.4 Higher Bandwidth (older version of esp8266 library - in my case 2.7.4) so then it was better, but still...

The Second was

invalid initialization of non-const reference of type ArduinoJson::JsonObject& {aka ArduinoJson6180_91::ObjectRef&}' from an rvalue of type 'ArduinoJson6180_91::enable_if<true, ArduinoJson6180_91::ObjectRef>::type {aka ArduinoJson6180_91::ObjectRef}

So i set older version of ArduinoJson(5.13.4) and seems to work...

but then I've got message from Serial Port:

In general time is showing 21:21:43, but in reality it was 23:21:43, so maybe it is making a Failed to connect to Azure IoT Hub?

What can I do to debug this?

Please help with this issue.
