changeip on 2.9

I found this script on the forums but I have a problem with it?

:log info "DDNS: Begin"

:global ddns-user "dakky21"
:global ddns-pass "my-password"
:global ddns-host "*1"
:global ddns-interface "T-Com ADSL"

:global ddns-system ("mt-" . [/system package get [/system package find name=system] version] )

:global ddns-ip [ /ip address get [/ip address find interface=$ddns-interface] address ]

:if ([ :typeof $ddns-lastip ] = nil ) do={ :global ddns-lastip 0.0.0.0/0 }

:if ([ :typeof $ddns-ip ] = nil ) do={

  :log info ("DDNS: No ip address present on " . $ddns-interface . ", please check.")

} else={

  :if ($ddns-ip != $ddns-lastip) do={

    :log info "DDNS: Sending UPDATE!"
    :log info [ /tool dns-update name=$ddns-host address=[:pick $ddns-ip 0 [:find $ddns-ip "/"] ] key-name=$ddns-user key=$ddns-pass ]
    :global ddns-lastip $ddns-ip

  } else={

    :log info "DDNS: No change"

  }

}

:log info "DDNS: End"

But when I click Run Script, it says in the log:
(script info) DDNS: Begin
(script info) DDNS: Sending UPDATE!
and then it says
(ddns error) Authentication Failure

What am I doing wrong? Please help.

I also tried typing the following command in the terminal:

/tool dns-update name="dakky.dns1.us" address=89.172.1.2 ke
y-name="dakky21" key="my-password"

And then it got updated OK…

Thank you for help,
Dakky

send this to support@changeip.com and we will investigate - possibly it’s a password mismatch or something.
