SIM7000 / GOBLIN 2 / Arduino GET variable does not work

I can’t seem to be able to GET the last two values of variable: (not even the last value)

    Serial1.println(F("AT+CIPOPEN=0,\"TCP\",\"industrial.api.ubidots.com\",80"));
    delay(3000);
    Serial1.println("AT+CIPSEND=0,177");
    delay(1000);
    Serial1.println(F("GET api/v1.6/devices/gps/position/values/?page_size=2 HTTP/1.1"));
    delay(50);
    Serial1.println(F("Host: industrial.api.ubidots.com"));
    delay(50);
    Serial1.println(F("X-Auth-Token: MY TOKEN"));
    delay(50);
    Serial1.println(F("Content-Type: application/json"));
    delay(50);
    Serial1.println("");
    delay(50);  
    Serial1.write(0x1A);
    delay(3000);
    Serial1.println(F("AT+CIPCLOSE=0"));

I get the answer:
RECV FROM:169.55.61.243:80
+IPD311
HTTP/1.1 400 Bad Request

I am able to write to this variable with no problem using the POST command.

What can be the problem?
