Change your password - now

You just posted your Base64 encoded username and password for your account. It will take about 3 seconds for somebody to turn that encoded string into your username and password. Oh, and there's no point obfuscating one instance of your hostname, but leaving all the others.

As explained here, your problem is either that your request is invalid or Dyn are refusing the user agent string since that device is known to be broken.
