Welcome to the Forums @Zipquestion! Thanks for sharing your experience with the Zip tracker and for all the troubleshooting steps you performed before posting here. 

To make sure that your app is working correctly, log out from your app and reboot your phone. Once your phone is up, log back in. After this if your are still experiencing an 400 error, try the steps recommended on the help article Why can't I update my Fitbit device?

I hope this helps, keep me posted! 😉

Hi Lucy,

Please help me. I have tried all available options. I’ve tried everything. Reset. Log out of app. Adding a new device. Replacing a device. It doesn’t work. Still error 400

Thanks

Hey there @Zipquestion! Thanks for the update. I really appreciate all the time and effort you have invested to solve this. Please make sure your Zip has enough power, 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 the firmware update again. If it doesn't work, reboot your mobile device and try the update again.
3. Try the firmware update again. If it doesn't work, on a different mobile device or computer (if available) log into your Fitbit account and try updating your firmware.

Let me know the outcome! 😉

I am having the same issue.  I have removed the app, shut down my phone, restarted the zip, tried to connect it to my computer.  I disconnected it from the app and tried to re-connect, and I can't connect it either.  The bluetooth finds the zip, but then the final connection does not complete.  What other options are there?

Error 400 continuously appears while trying to set up Zip. I see many, many others experiencing same problem. You don't seem to be providing any help, which is quite frustrating. I've tried everything you have suggested, several times, to no avail. Please help. I beginning to think that Fitbit is perhaps the wrong fit for me.

Nothing is working for me. I can get a different zip to not generate the error 400 and sync properly with my iPhone, but not my Zip.

Please help

Hi Lucy

Like others we have the same error and can't seem to get the Zip to connect to my iPhone 5s. It stopped syncing for some reason so I removed the device but now it won't setup again as we get the error 400 message.  We have tried removing app, updating app, power off (both phone and zip), removing battery from zip but still no luck in setting it up. What are we doing wrong?  Please help.

Thank you for asking if the issue with my Zip and not syncing with my iPhone has been resolved. Two updates ago, my iPhone SE no longer communicates with my Zip. I have like other Zip users to avoid the Error 400 issue with no luck

I find myself in the same situation with my zip ... error 400.  My zip was working fine for years ... even on my iPhone 7 until about 2 months ago.  I tried to get it to reconnect several times and was just going to toss it, but I had a few minutes today to try to research it a bit.

I have tried ALL the suggestions here ... I have even deleted and re-downloaded the app ... to no avail.  My phone app finds the zip, asks for the 4-digit code then I get the following message.

The operation could not be completed.

(com.fitbit.HTTP error 400)

Any help would be appreciated.

[Zipquestion]

You are not alone. I tried everything. No long luck.
