Problem with limited connection

[AgentCousto]

Hello,
I use the AWS SDK to push files daily to S3.
I have an upload connection close to 100KB/s, and I'm trying to send files of size 50MB.
I don't understand why my files are not uploading I have the following messages in the AWS logs:

[WARN] 2023-11-24 00:11:28.191 WinHttpSyncHttpClient [11144] Send request failed: La connexion avec le serveur a été interrompue anormalement

Thanks for your help

Is the time on the machine you are running this correct? Your getting this error:

If the signature check failed. This could be because of a time skew. Attempting to adjust the signer.

Which suggests that the time might be incorrect. If the time is more than 15 minutes off from what the AWS servers expect on the signatures then this can cause issues. This sdk will try to resolve the errors but it doesn't always work. Can you confirm that you have the correct time (or close to) on your machine.

If that doesn't work can you provide the following:

• a minimal reproduction sample
• C++ sdk version
• OS version
• how you are compiling/building this sdk

Thank you for your response, the SDK runs on a boat that sails from Europe to America. My PC is running Windows 10 and the clock is in UTC synchronized via the internet. Could it be a time zone problem?

[jmklix]

It could possibly be a time zone problem and that is a cool and unique scenario that you are in. Did moving to a different time zone cause this to start failing?
