Why does AWS S3 PresignedPost function properly on a local platform but encounter an ERR_CONNECTION_RESET error on the production platform?

edit

There could be several reasons why the AWS S3 PresignedPost function works on a local platform but encounters an ERRCONNECTIONRESET error on a production platform.

One possible reason could be a network connectivity issue. The production platform may have a stricter firewall or network configuration that is blocking the connection to the AWS S3 service.

Another possibility is that there is an issue with the configuration of the AWS S3 bucket or the IAM role used to generate the presigned URL. It is possible that the permissions or policies are not properly configured on the production platform, which is causing the connection error.

Additionally, it may be related to the version of SSL/TLS protocol being used. The production platform may require a more up-to-date version that is not supported on the local platform.

To resolve this issue, carefully review the network configurations, permissions, policies, and SSL/TLS protocols used on both the local and production platforms to identify any discrepancies or misconfigurations.
