It is all working quite well most of the time, but sometimes the call to mbedtls_ssl_handshake() never returns. So both behaviors (failed or success) should be OK, right? If yes, I think maybe a configuration for succeeding the handshake if signature_algorithms extension is empty should be added to the mbedtls. when I call mbedtls_ssl_handshake fucntion, the function failed, the mbedtls err Once the connection is terminated FW waits for a new client connection and call again mbedtls_ssl_handshake. 12 (esp32-idf3-20191220-v1. 99:8090 E (16173) WebSocket: Failed to connect to server E (16183) Application: Failed to connect to websocket server Summary.
