Good day. Thank you for your question.
May I know if you have tried sending the SMS/GPRS command "web_connect" to the device after creating a task for updating the configuration via FOTA WEB? For more information on the SMS/GPRS commands, please refer here - https://wiki.teltonika-gps.com/view/FMB_SMS/GPRS_Commands
