Mbedtls_ssl_handshake returned -0x7100

Mbed TLS

Hi, I am new to Mbed TLS, and I am attempting to establish a connection to AWS using a PSoC microcontroller with a W5500 module. I have successfully ported the AWS SDK and Mbed TLS for my project, but I encountered a handshake failure with error code -0x7100. Please review the log below. Does anyone have knowledge of this error?

Hello,

how you can see the Mbed TLS category of Mbed support forum is not very active, and MbedTLS was moved - Announcement: Migration of Mbed TLS.
