Http prefix to remote server name

I’m working with HL7812 FW v and using freeRTOS Cellular library.
I have situation where passing one address pattern - connection success and other - fails :

One which fails :

AT+KTCPCFG=1,0,\"\",80", '\0'

And I’m receiving URC NOTIF : DNS error after calling


One which succeed :

AT+KTCPCFG=1,0,\"\",80", '\0'

There is a problem with passing http or the “//” of http , to KTCPCFG ?
What will be correct steps to handle such error from cellular module’s point of view ?

That parameter should only contain ip address, so http string should not be included
