S3 Presigned URL getting expired within 1 hour

[DeweshTiwari]

I have certain files at S3 bucket, and generating presigned url programmatically to access those files , Even though i am setting expire time as 7 hours (setting correctly as X-Amz-Expires = 25200 ) it is getting expired after an hour .

If you are using temporary credentials to generate the presigned url, check if they expire in one hour.

The actual expiration of a presigned url is the minimum between the credentials and the presigned url expiration time.
