Greetings,
As of firmware version 7.14, direct HTTP POST/GET requests have been removed from Teltonika devices. These functions are now handled through a more secure API interface.
You can learn more about the removal of POST/GET services here: Implementation of Read-Only System Files and Mobile and I/O POST/GET Service Removal with RutOS 7.14
For detailed information and examples on using the new API, please visit:https://developers.teltonika-networks.com/
Best Regards,
Justinas
