I have been facing an issue recently, when I am accessing the private s3 files, sometimes the files get displayed and sometimes doesn't. Mainly the issue is happening with Google Chrome. The file is accessed through PHP library provided by Amazon S3, the url is like
https://s3.amazonaws.com/{bucket_name}/{file_name}?AWSAccessKeyId={access_key}&Expires={expire_time}&Signature={signature}
No change has been done to configuration as these files were running smoothly before this issue!
Please help me.
