mbedTLS Handshake error

Postby yuya0629 » Fri Jan 14, 2022 9:02 am

Currently, HTTPS communication is performed with ESP32-WROOM-32D.
The version of ESP-IDF is 4.2.

I have downloaded and used the root certificate from the server I am accessing, but I get the following error.

E (34597) esp-x509-crt-bundle: Failed to verify certificate
E (34598) esp-tls-mbedtls: mbedtls_ssl_handshake returned -0x3000
E (34599) esp-tls: Failed to open new connection
E (34606) tls: Connection failed ...

The certificate used is [Security Communication Root CA2].
Communication is possible with [Security Communication Root CA1] without any problem, but I would like to use [Security Communication Root CA2], which has a long certificate expiration date.

Does anyone know the cause?
