could give me other test to do ?
thanks

Is the device running the app connected to the same network (via Wi-Fi) or is it connecting via GPRS?

Do you have a static public IP address, and if not what sort of DDNS service are you using?

What custom server settings are you using in the app?

Pete.

yes the app is connected via wifi but the server is with cable
i tested on local lan 192,168.1.10 (server) - 192.168.1.12 (app)
now i test to load the blinlk server on the pc W10 in lan and works but has different IP and the borad can’t connect
i tested to reinstall java 8 because i think is one security issue on JAVA but on synology i don’t know how enable JAVA on lan
