Forward confirmed reverse DNS failing

[FedericoArg]

Hi Fitbit Team, since last week our Subscriber started failing due to a problem when validating the IP address of the incoming HTTP Message.

We would like to know if the following IPs belong to Fitbit as they seem not to be resolving to a Fitbit domain:

(e4.91.2da9.ip4.static.sl-reverse.com). IP:[169.45.145.228]
(f3.91.2da9.ip4.static.sl-reverse.com). IP:[169.45.145.243]
(f4.91.2da9.ip4.static.sl-reverse.com). IP:[169.45.145.244]

@FedericoArg Thanks, we're looking into it.

@FedericoArg This should be fixed now.

@AndrewFitbit We have seen similar failures week of 4/16/2017 - 4/20/2017.  Is it possible this has resurfaced?
