Tried connection of RAK to Network Server

Im new with all this stuff. Tried a few ways to connect to Network Server.

My goal is: to get my end device (Libelium) to send data to Network Server. Then, the network server sends the data to the Https for me to do data virtualization.

Im thinking of using the build-in Network Server in RAK 7249

Can u guys carify if im missing any ways. Can i use the build-in Network Server to send to Https or any method that is available?
