mbedtls handshake failed 0x7780

[Anon767]

Hey,

I tried the SSL_Client mbedtls example program for the STM32f7 and I get following error:

Handshake failed 0x7780

Im trying to connect to a cloudflare server via https.

Any ideas what the problem could be?

thanks in advance

seems like this refers to #define MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE 0x7780
