UC20 +CME ERROR: 714 HTTP DNS ERROR

I have a QUECTEL UC20 and I need to send the coordinates via HTTP to a server in the cloud. For this I am using the following commands:

AT+QICSGP=1,1,“APN”,"","",1
okay
AT+QIACT=1
okay
AT+QIACT?
+QIACT: 1,1,1,"-------"
okay
AT+QHTTPCFG=“contextid”,1
okay
AT+QHTTPCFG=“responseheader”,0
okay
AT+QIDNSCFG=1,“8.8.8.8”,“8.8.4.4”
okay
AT+QHTTPURL=43.20
CONNECT
okay
AT+QHTTPGET=80
okay
+QHTTPGET: 714

Then I get that error about DNS, error 714… Does anyone know why it happens?

AT+QIDNSCFG=1,“8.8.8.8”,“8.8.4.4”
AT+QIDNSGIP=1,"<domain_name>"

I get that error, which is invalid parameters

When I enter the domain IP, it does not give me an error, but when I run AT+QHTTPGET=70 again, it gives me error 714.

I recommend checking whether your HTTP server requires CA authentication, or switching to another HTTP URL for debugging
