SSL: switched to detect log level based on the last error. In some cases there might be multiple errors in the OpenSSL error queue, notably when a libcrypto call fails, and then the SSL layer generates an error itself. For example, the following errors were observed with OpenSSL 3.0.8 with TLSv1.3 enabled: SSL_do_handshake() failed (SSL: error:02800066:Diffie-Hellman routines::invalid public key error:0A000132:SSL routines::bad ecpoint) SSL_do_handshake() failed (SSL: error:08000066:elliptic curve routines::invalid encoding error:0A000132:SSL routines::bad ecpoint) SSL_do_handshake() failed (SSL: error:0800006B:elliptic curve routines::point is not on curve error:0A000132:SSL routines::bad ecpoint) In such cases it seems to be better to determine logging level based on the last error in the error queue (the one added by the SSL layer, SSL_R_BAD_ECPOINT in all of the above example example errors). To do so, the ngx_ssl_connection_error() function was changed to use ERR_peek_last_error().
