Error 400 when trying to set up my Zip.

[CW12656]

I keep trying to set up my fitbit zip on my iphone.  It gets to the part where it asks for a code.  I get the code off of the zip and type it in,  I immediately get a 400 error code and try again and get new code and same thing.  This has been happening for days.  Anybody know how to fix it?  So annoying!  Thanks!

Hello @CW12656, have a warm welcome to the Fitbit Community, it's great to have you on board. 

I appreciate your participation in the Forums and for sharing your experience with us. At this moment I would like to suggest you to make sure your tracker is fully charged and then try these steps:

1. Turn your tracker off and on again using the instructions in How do I restart my tracker?
2. Try to set up your device again. If it doesn't work, reboot your mobile device and try again.
3. Try to set up again. If it doesn't work, on a different mobile device or computer (if available) 

   Note that if you get notifications from your mobile device on your tracker, before you can use a different device or computer you need to follow the instructions in Why is my tracker only syncing with one mobile device?

I hope this can be helpful, if there's anything else we can do for you, please feel free to reply.

Tried all the steps listed above and used 2 different devices to no avail.  Support is no longer available; so who can help?!?
