Can you post some debug info? It looks like it did not get command confirmation.

Log files are in log folder under systemlogger.log, but it's delayed. The easy way is to debug from console. You stop server (Config->General settings->Shutdown server) and then start server sudo mono EasyIoT.exe. See tutorials for details.
If you just start with NRF24L01 first check if NRF is properly connected to Raspberry (you should see some NRF initialization info in console after EasyIoT server startup). Also be sure to use right channel and connection speed for NRF in Arduino code and EasyIoT server.
