HELP. (ESP32) with mbedtls_ssl_handshake returned -28800
Posted: Wed Jun 02, 2021 11:00 am
Hello,
I have a project where I have used ESP32 to connect with Amazon AWS cloud. Everything was working good but suddenly my device is not able to connect to the aws cloud. The error logs show the following
Failed! mbedtls_ssl_handshake returned -28800
I then converted -28800 to hex generates 7080
As per the SSL error code this translate to
#define MBEDTLS_ERR_SSL_FEATURE_UNAVAILABLE -0x7080 /**< The requested feature is not available. */
I checked the certificates and they have a valid and future date.
Can someone help me to understand the possible cause for this ? Would be highly helpful
Thank you
