HL7800 DNS error

Hi!

I’m trying to connect to our server, but I’m getting a DNS error. If I change to the IP address, everything works fine. Look bellow:

what is the possible source of this problem?

best regards,

I don’t see problem with FW 4.6.8.0:

+CEREG: 1,"0001","01A2D001",7

+CREG: 1,"0001","01A2D001",7
AT+KCNXCFG=1,"GPRS","internet"

OK

HL7800.4.6.8.0

OK
AT+KTCPCFG=1,0,"www.google.com",80

+KTCPCFG: 1

OK

ok.
I’ll try to update the firmware.

I’m also dealing with problems to perform this task:
