Unable to Access Due to Client Certificate Error

When you try to access an URL that requires client certificate authentication (https://subdomain name.s.kintone.com/), an error message ("A client certificate is required for access. Code: 496 No Cert") might be displayed to prevent access.

You must register a client certificate to your Web browser in order to use the Client Certificate Authentication.

  2. Reboot the Web browser.
