mbedtls_ssl_handshake returned -0x7780

[yasiralijaved]

I am stuck for days into this problem with ESP32 WROOM 32D. I created a thing in aws iot core and downloaded the certificates. Then setup the tls_mutual_auth example in VS Code from https://github.com/espressif/esp-aws-iot/tree/master/examples/mqtt/tls_mutual_auth. Modified the cert folder with downloaded certificates but getting the error. Although the same certificates are working FINE when using MQTTX in Windows, it can connect, subscribe and publish without any issue.

esp-tls-mbedtls: mbedtls_ssl_handshake returned -0x7780
esp-tls-mbedtls: Certificate verified.
