Hello, I set up the Google IoT core settings for the example and build successful. But after executing it with idf.py monitor command, the data does not come into IoT core. (IDF version: v4.0) I checked with ESP_LOGI and an error occurs in the function below.

...
I (5974) APP: Initializing SNTP
I (5974) APP: Waiting for system time to be set...
I (7984) APP: Time is set...

I (8094) mqtt_task: iotc_create_iotcore_jwt returned with error: 71l

The error code is IOTC_JWT_FORMATTION_ERROR. Could you check this problem?

Check you Private Key, make sure it's correct and includes ------BEGIN EC PRIVATE KEY------ and ------END EC PRIVATE KEY----- and everything in-between

@meltdown03 , do you have any lights on what could be happening for testing other ways?

No, sorry, I never got this error.

Hi! I was able to solve the problem by creating elliptic curve keys.
