We have Mac and Windows apps that access online data files frequently. These are used for weather and earthquake data, among other things. Our files are hosted on a Amazon CloudFront distribution backed by an S3 bucket.
Recently, people who are using ExpressVPN on Macs are getting 403 errors and "ClientHungUpRequest" results from CloudFront.
On the Mac side, we are using NSURLSession
and everything works fine without ExpressVPN.
Is there anything we can do about this, or is Amazon doing something to block ExpressVPN IPs from being able to access our hosted files?
