# ERROR after a few AT+CIPSTART... requests

## Question

Asked by msemegen on 2022-12-06 in Wireless.

Hi,

after a few (about 35) “AT+CIPSTART="SSL","www.google.com",443\r\n” requests I get “ERROR” response from module.

Before that I set:
“AT+CIPMUX=0\r\n”
“>OK”
“AT+CIPSSLSIZE=4096\r\n”
“>OK”

Does anyone has idea what is going on?

Best,
Mateusz

Hello [@msemegen](https://maker.wiznet.io/u/msemegen)

Did you connect to Wi-Fi before using ‘AT+CIPSTART=“SSL”,“[www.google.com](http://www.google.com)”,443’ command?

Yes,

I’m connected.

I reproduced Yours settings and situation is the same. First connection is successful but after some time (connecting and disconnecting with [google.com](http://google.com) with 500ms delay) I’m starting to receive “ERROR” response.

As I can see, I have pretty old module FW:
“AT version:1.0.2.5(Aug 23 2019 17:03:59)
SDK version:3.2.0(a0ffff9f)
compile time:Aug 23 2019 17:00”

Ok,

updating FW to latest version, probably fixed the problem!

Best,
Mateusz
