DFOTA error 711 (BG77)

IoT Modules LPWA Module

HI,
I am in the process of implementing DFOTA (BG77) but unfortunately I get every time:

+QIND: “FOTA”,“HTTPEND”,711

I tested it with HTTPS but also with HTTP
I use the following commands:

AT+QCFGEXT=“fota_apn”,1,“xx”,“”,“”
OK

AT+CSQ;+CEREG?;+COPS?

+CSQ: 30,99

+CEREG: 2,5,“109”,“5751479”,8

+COPS: 0,2,“20416”,8

OK
AT+QFOTADL=“xx”

OK

+QIND: “FOTA”,“HTTPSTART”

+QIND: “FOTA”,“HTTPEND”,711

Hi @JasperLI

Which SIM/network are you using? and have you set correct APN? according error code 711 means data call disconnect, So, this is probably your network issue.
