status code -2 not able to get correct response #101
Comments
The following fields are missing: Description, Steps to Reproduce, Expected Behavior, Actual Behavior, Environment, IDE. Please update the issue with this information. |
HI @Manojkumar0308 Generally, -2 reflects something occurring at the transport layer - the one level down from this. So the TinyGSM transport. -2 often reflects some sort of timeout - i.e. flaky connection. Are you in Arduino IDE or PlatformIO? Be good to see you code and also some debug level serial output. |
I am using Arduino IDE Sir

15:03:39.784 -> [3495] Connecting to Whats wrong with this example https_7600.ino why i am getting this I am using this module https://github.com/Vajravegha/VVM501_ESP32_4GLTE_MODULE/blob/main/Datasheets/VVM501%20ESP32%204G%20LTE%20MODULE.pdf |

check my code |
-2 is coming from HttpClient library. As a timeout as in a lack of response on that endpoint. You should check you cert. You are setting it with root_ca but I don't see the include? is this in ssl_web.h? Other thing I would check is Serial.print() the server url and resource just before making the GET request. You can also capture and output the return value of the GET request itself. Have a look at the HttpClient code for what to expect for success and fail. |
//CA Certificate for www.howsmyssl.com (valid until 12-03-2027) The certificate is also correct i just copied your code its not a problem with httpclient i guess its fail to set certificate use any library including ArduinoHttpClient library still i am getting the same. I am using ESP 32 -WROOM chip with A7672S simcom module |
Okay I have just visited const char root_ca[] PROGMEM =

which microcontroller you are using sir.I will do it for tomorrow then i
will use the given certificate by you and just copy paste your code and
will see the output sir i will change SIM800L to SIM7600 because i am using
it with esp 32 wroom microcontroller.
