Hi,
I'm using self-signed certificates/keys for https server on esp32-s3 board and client on my phone, it fails in handshake phase, see below errors:

I (19095) esp_https_server: performing session handshake
E (19115) esp-tls-mbedtls: mbedtls_ssl_handshake returned -0x7280
E (19115) esp_https_server: esp_tls_create_server_session failed
E (19125) httpd: httpd_accept_conn: session creation failed
W (19125) httpd: httpd_server: error accepting new connection

FYI, the key length is 2048 bits, http works fine. Does anybody know what this error code means? any suggestions? thanks.

how can I detect the esp32-s3 board hostname? I used ping -a 10.0.0.15, and it didn't work. Thanks.

The server didn't like something about the client's handshake. Ensure they are using the same cypher suites.

Why not spit out the current IP over the serial terminal?

Thanks, I have figured out and made it works. Please can someone help me close this tickets? thanks!
