"Sorry, you have been blocked" message by CloudFlare, cannot make submissions [FIXED]
By sohailkazi, history, 4 months ago, In English

Cloudflare has suddenly blocked me from making any submissions from my account. Any time I try to submit a solution, I get redirected to a CloudFlare page that informs me that I have performed some action that has triggered a security solution. The rest of the website works fine however, which means my codeforces account is fine, but Cloudflare has erroneously flagged my account for some reason.

Cloudflare Ray ID: 8b796031cf9c3b49.

Can some site admin please help?

EDIT: As suggested by user crystaI, making submissions from the mirror website works.

EDIT2: Thanks MikeMirzayanov, issue seems fixed.

same problem , But it works so strangely. The error lies in the fact that it is issued for a certain code, it seems to me that this is due to certain characters or commands.

The line in the posted link is one of the culprits. You can verify this by commenting the above line in one of your submissions. As long that line is present in your code, you won't be able to submit it. As soon as you remove it, you will be able to submit your code again. I can't even post a comment with that line, I had to use pastebin.

    s[i] = char(j + 'a');

    Let's see if I can comment this line or not. If this gets commented, that means it's only applicable to a specific location or some specific service users.

The code in the link is causing the blockage in my implementation, as said by sohailkazi you can't even comment this line.

I am facing the exact same issue. I don't know why this is happening to me. Codeforces, please look into this issue, I am unable to practice as well.

    There have been incidents before where someone DDoSes Codeforces during a round after getting a poor performance.

    (Although I suspect that the CloudFlare configuration Codeforces uses is overzealous.)

Hello. I've reconfigured some settings on the Cloudflare side, but in such cases, please report to me as described here: https://codeforces.net/blog/entry/133113
