@Rasyid Do you have a valid network connection ?
For Quectel BG96 you can verify the network connection with the following AT commands
AT+CGPADDR //check IP address
AT+CGATT? //check if attached to network
AT+COPS? //check current set MNO
AT+COPS=? //scan network for mobile operators
AT+CGDCONT? //check APN
AT+QPING=1,"172.27.131.100" //ping UDP server
