It looks like one of our IP addresses has been blocked from accessing the REST API.
Any request to the API from the blocked IP address returns a generic “403 Forbidden” response:
<html> <head><title>403 Forbidden</title></head> <body> <center><h1>403 Forbidden</h1></center> </body> </html>
It doesn’t appear to be the API credentials as they continue to work when used from other IP addresses.
Is it possible to get an IP address unblocked from the API?
