pioarduino: esp_https_server fails to start

[mhaberler]

trying the Arduino3 community fork

both stable and develop show same behavior - esp_https_server fails to start

cert and key are definitely present

this looks like an sdkconfig issue to me, possibly around mbed_tls

platform = espressif32@6.7.0 works fine btw

=========== After Setup Start ============

The community Platformio build uses the officaly 3.0.3 release from espressif server. So it is 100% same as when using ArduinoIDE. So not an Platform problem. platform = espressif32 @ 6.7.0 is using Arduino core 2.0.16

Looks like a issue with Arduino Core 3.0.3 in general

while I have not fixed this particular issue yet, I have made progress towards HTTPS servers which work well with the Arduino3 community fork:

https://github.com/mhaberler/esp32_https_server/tree/pioa3-test https://github.com/mhaberler/esp32_idf5_https_server_compat/tree/pioa3-test

both are based on recent work by @jackjansen and needed a minor brushup to get past the mbed_tls API changes which happen around ESP-IDF 5.0.2

they are descendents of the abandoned https://github.com/fhessel/esp32_https_server

however, they are NOT based on the ESP-IDF esp_https_server component like PsychicHTTP AFAICT

Could this be the same issue as #93?

@mhaberler, can you try enabling the idf logs to see if you get any more information? I wonder if it will also print a message saying that no certificate was supplied.

[mhaberler]

yes, very likely so - same symptoms

looking into it

[mhaberler]

it comes down to a difference in struct httpd_ssl_config - V5.0.2 and later expect an additional servercert and servercert_len to be passed

if I change PsychicHttpsServer::listen like so:

esp_err_t PsychicHttpsServer::listen(uint16_t port, const char *cert, const char *private_key) {
    this->_use_ssl = true;

    this->ssl_config.port_secure = port;
    this->ssl_config.cacert_pem = (uint8_t *)cert;
    this->ssl_config.cacert_len = strlen(cert)+1;

    this->ssl_config.servercert = (uint8_t *)cert;
    this->ssl_config.servercert_len = strlen(cert);

    this->ssl_config.prvtkey_pem = (uint8_t *)private_key;
    this->ssl_config.prvtkey_len = strlen(private_key)+1;

    return this->_start();
}

the https server starts up fine and accepts a connection

it fails later due to servercert expects something different than cacert_pem and parsing the cert fails, but that is to be expected

so I'm hopeful, need to read up on migration

fixed via https://github.com/hoeken/PsychicHttp/commit/98dec76f4c9dc5da1c1478ac6dddfd1449101b76

thanks @hoeken !
