Firebase storage error 1200 over wifi only, LTE works perfectly

[tennydesign]

This error started to pop this week. It is really weird. Code is just a simple putdata on Firebase Storage to save an image. (Swift 5 // XCode 11.3.1)

• Xcode version: 11.3.1
• Firebase SDK version: 3.5.0
• Firebase Component: Storage
• Installation method: `CocoaPods

    storageRef.putData(profileImageData, metadata: nil, completion: { (metadata, error) in
        if error != nil {
            print(error!)
            completion?(nil)
            return
        }
        storageRef.downloadURL(completion: { (url, error) in
            if error != nil {
                print(error!)
                completion?(nil)
                return
            }
            completion?(url?.absoluteString)
        })
    })

Then what I get back over LTE is: Success. What I get back over my home Wifi (xfinity-USA) is:
