Submission fails due to the redirect

ARC White-Box Estimation Challenge 2026

Hello.

All my attempts to submit fails with the error:

Submitting to AIcrowd
Uploading artifact to S3
⚠ Submission failed: AIcrowd API error (302): <html><body>You are being <a href="https://www.aicrowd.com/">redirected</a>.</body></html>

And i don’t understand what exactly i’m doing wrong.
Please advise me what can be the problem.

Thanks.
