Facing Cloudflare Verification Issues During Contest Submissions

Revision en1, by falcon07, 2025-09-21 14:55:04

Hello everyone,

I am facing a repeated issue while participating in Codeforces contests, and I want to bring it to the attention of the site administrators, especially MikeMirzayanov.

Whenever I try to make a submission during contests, before every single submission I am forced to go through a Cloudflare verification page. This becomes extremely frustrating because: - It slows me down in a time-critical environment as after going through verification process i need to resubmit the problem. - Sometimes, the verification process doesn’t resolve properly and I am forced to log out and log back in again just to continue. Why there is a need to verify again and again that i am a human, I understand that Cloudflare protection is important for site security, but this issue seems specific and excessive. It is not a one-time captcha but something that happens before every submission and that too only in contests, which ruins the contest experience. During Practice this rarely happens with me.

I kindly urge the admins to look into this problem and fix it. If there are specific settings or account-related reasons why this is happening only for me (or for a subset of users), I would be grateful for guidance from my CF community on how to resolve it.

Thank you

I have attached the image of human verification page which appears before each submission
