2259971 - Cannot overcome TLS handshake error


  • When making a web client procedure call to a website the following error is returned: The secure connection to the remote host failed: The TLS handshake failed, error code 0
  • WireShark traces shows TLSv1.2 Record Layer: Alert (Level: Fatal, Description: Handshake Failure)
  • Looking at the Client Hello packet in the WireShark trace the certain Cipher Suites are offered by SQL Anywhere
    • For example:
      • TLS_RSA_WITH_AES_256_CBC_SHA  (0x0035)
      • TLS_RSA_WITH_AES_128_CBC_SHA  (0x002f)
      • TLS_RSA_WITH_RC4_128_CBC_MD5  (0x0004)
  • Looking at the list of supported Cipher Suites in the a browser the web server picks a Cipher Suite that is not offered by SQL Anywhere
    • For example:
      • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256  (0x0035)
