WebApp subscription endpoints are not reached by verify requests

[piotr-zywien]

Hi everyone, @JeremiahFitbit, @AndrewFitbit, @DavidSFitbit, anyone (please help, also thank you!) 🙂

I am wondering why in the dev web application console, it would be not possible to verify some servers and not others.

Are there any limits, are there blacklists?

I have verified that the test server in question is:

- open for inbound requests

- receives requests from other sources

Also I have verified that:

- other servers with the same domain can receive verify requests

- there is already a working, verified subscription working with our production servers

The only conclusion, I have come to is that there is a blacklist on Fitbit's side, as on our side, we can see in our access logs that:

- Fitbit is able to reach our production servers

- is unable to reach our test servers (irrespectively of the verification token)

- any non-Fitbit verification request is able to reach our test servers 

I appreciate any help you can provide! 🙂

Thanks,

Piotr.
