UG96 - stuck with 711 error on connect to https


I am having trouble in getting my UG96 start a ssl connection.
I am following exactly (or, I think) the step of the application note:

-> AT+QHTTPCFG=“sslctxID”,1





->I print out the 22 bytes of + \r and always get error 711.

I know that 711 is malformed URL but I’m at total loss on this.

I’d like to know, byte-by.byte, the EXACT sequence of bytes that shall be transmitted to the modem, maybe I’m doing something wrong with line terminations, IDK.

From the begin of the command “AT+QHTTPURL=22,80” till the end of the url what is the exact sequence to send? Line terminations included.


I assume you want to access HTTPS.The server port needs to be set to connect HTPPS。
Such as:

Thanks! This solved the issue and it says “OK” and yes I’m attempting an https connection.

At the next step “AT+QHTTPGET=80” I get and error 705. What is it?

In order not to waste your time, do you please have, applicable to UG96, an application note with the error codes explained? “HTTP NO GET/POST REQUEST” is an error description that doesn’t help me much :slight_smile:


Problem can occur if some or all of the following services aren’t started:

  • Plug and Play
  • Remote Access Auto Connection Manager
  • Remote Access Connection Manager
  • Telephony

To fix this problem, follow these steps for each of the services listed above:

  • Open Administrative Tools by clicking the Start button, and then clicking Control Panel. In the search box, type administrative tools, and then click Administrative Tools.‍ If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
  • Double-click Services. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
  • Right-click one of the services listed above, and then click Properties.
  • Click the General tab, and then, next to Startup type, select Manual.
  • Click Apply, and then click Start.

Hope this helps,

Thanks Jimmy,
so you are saying realistically it’s a server side issue?
Because I’m connecting from a microcontroller, sending AT commands to the modem over a serial line.

If so, my best bet is to do the connection tests pointing at something like “howismyssl”?
