HTTPS example doesn`t work on U-BLOX Odin W2

I try to build HTTPS example on ODIN W2 and got the next problem:

Connecting to os.mbed.com:443
Starting the TLS handshake...
mbedtls_ssl_handshake() failed: -0x2700 (-9984): X509 - Certificate verification failed, e.g. CRL, CA or signature check failed

Error flag sets in file x509_crt.c, line 1925:

    if( x509_profile_check_pk_alg( profile, child->sig_pk ) != 0 )
        *flags |= MBEDTLS_X509_BADCERT_BAD_PK;

Anyone have ideas?
