putObjectWithFile: returns NSURLErrorDomain -1012 with AFNetworking 2.5.3 + AFAmazonS3Manager 3.2.1

[fitch]

I started getting NSURLErrorDomain -1012 on every putObjectWithFile: call (Xcode 6.3.1 + Swift + iOS 8.3 on iPhone 6) when I upgraded AFNetworking to 2.5.3.

File upload failed with error: Error Domain=NSURLErrorDomain Code=-1012
"The operation couldn’t be completed. (NSURLErrorDomain error -1012.)

With AFNetworking 2.5.2 it works fine. I'm using AFAmazonS3Manager and AFNetworking with CocoaPods 0.36.3 along with these pods:

Using AFAmazonS3Manager (3.2.1)
Using AFNetworking (2.5.2)
Using Firebase (2.2.2)
Using SDWebImage (3.7.2)
Using SVProgressHUD (1.1.3)
Using UIAlertController+Blocks (0.9)

Any update on this? My code was working up until when 2.5.3 came out and now I get this same error.

I have the same problem. It works fine with AFNetworking 2.5.2.
