Download AWS S3. Invalid by policy: policy has expired.

I am using a Django server hosted in EC2 Singapore. I also use the S3 bucket to save files uploaded through the Django admin panel. To upload files, I use django-s3direct .

When I upload files using my local machine in East American time, this does not allow me to upload files that link to:

 <Message>Invalid according to Policy: Policy expired.</Message>

I tried solutions from:
The exact recipient download of "Policy expired" sending a message to S3 for some here too: https://github.com/FineUploader/fine-uploader/issues/1387

When I check the boot time and UTC time, there is no difference. How to fix this error?

EDIT: It should be noted that the download works fine on the local host, but does not work on the server hosted on AWS EC2.

Similar problems apply to inaccurate watches. It should be a client clock, not a server. I suggest writing code to check if client time is synchronized with a known and accurate time server. If the time is not synchronized, the user may be shown a friendly message to update the system clock. If the time is synchronized, you can continue to download.
