Why does CloudFront sometimes take about 10 minutes to get a new file?

Here's my situation, users upload their files into an S3 bucket, and I'm using CloudFront to deliver images files.

But I found when a user upload multiple images (around 4~5 pics, all new uploads, NOT UPDATES), at least one image won't be able to display instantly through CloudFront (AccessDenied error), but after around 10 minutes, the image will be able to show up correctly. But meanwhile, if I use a VPN connection located in other place, the image will show up instantly, so I believe it should be a problem in my local CloudFront endpoint.

My S3 bucket is located in the US West 2 region (oregon).

Is this situation common? I did a Google search, but I didn't see anyone complaining about the same problem, so I'm worrying if I did something wrong.
