Occasional 400 errors

Since October 23rd, my Fitbit Low Battery Notifier app is getting occasional 400 API errors when requesting user profiles to get battery levels.  It doesn't happen for every request, it's never the same users, and only happens on a few requests of an hourly batch.

 

The full response is:

<head><title>400 Bad Request</title></head>
<body bgcolor="white">
<center><h1>400 Bad Request</h1></center>
<hr><center>cloudflare-nginx</center>
</body>
</html>

I notice you're using CloudFlare; is it possible I'm hitting some kind of rate limit triggering CloudFlare's DoS protection?

Most likely. I will tell Fitbit's ops team to check on the IP addresses of your app's servers.

I'm experiencing the same type of problems across different api calls. This has been happening for at least a month and happens about 1 out of every 1000 calls.

@ScottQ: What is the content of the response when you get the error? If you're seeing a CloudFlare error, please contact us privately with your client id.

@JeremiahFitbit: Will this take some time to resolve?  I am still getting 400 errors every hour.

@JeremiahFitbit I have submitted this issue privately on Nov 3 and have not received any response from yet.

 

For over a month we have been receiving occasional 400 Bad Request errors. Is this error being investigated? Are there any plans to address this?

 

Thanks!

I also sent an e-mail to api@fibit.com a week ago and received an auto-reply but no follow up from anyone.  These errors are still persisting as of this afternoon.

I think I follow up with your email on Friday but the gist of it is we are troubleshooting this issue with Cloudflare and our operations team. We will let you know both via email and here once we have an update or resolution. Sorry for the inconvenience.

@jcs_@FedericoArg We've received a response and resolution from Cloudflare on this issue. Are you still seeing this problem?

@SunsetRunner Looks like the last Bad Request error we received was from 3 days ago (11/20/2015 10:08 AM Pacific).

 

Looks like the solution worked. I'll let you know if we encounter this issue again.

 

Thank you very much for looking into this!
