        1. Run $ sudo apt install chromium-chromedriver firefox-geckodriver
    If you use Ubuntu under Windows Subsystem for Linux:
        1. Make a symbolic link from cookie.jar in WSL to cookie.jar out of WSL. For example, run $ ln -s /mnt/c/Users/%USERNAME%/AppData/Local/online-judge-tools/online-judge-tools/cookie.jar /home/ubuntu/.local/share/online-judge-tools/cookie.jar
        2. Use `oj login` outside of WSL
    If you use Windows:
        1. Install Chocolatey. See https://chocolatey.org/
        2. Run > choco install selenium-all-drivers

@hotaroon Thank you for reporting! (This is well-written bugreport 😄)

Conclusion: Let me wait and see how it goes.

While waiting, the same issue will reported at cf-tool, or Codeforces may change the logic.
I'll investigate further when this is not fixed even after a while (in this weekend?)

Observation

I could reproduce the issue, but the precise condition is still unknown.
My observations are:

  1. At first, the submissions succeeded regardless the User-Agent. (User-Agent is irreverent)
  2. The first few times submissions succeeded, but after all submissions failed. (it seems "banned")
  3. Submissions from my GUI browser (Google Chrome) succeeds even after the "ban". (the "ban" is not associated with IP address nor account)
  4. However, after removing the cookie ~/.local/share/online-judge-tools/cookie.jar and re-login, submissions from online-judge-tools still fails. (the "ban" is not associated with the session)

There are many difference between HTTP requests from online-judge-tools and from GUI browsers (e.g. referer, CSRF token, etc.), so probably one of them is the cause.

I merged a commit #120 to fix this issue.

I think this is fixed, but it's difficult to prove that this types of problems are truly fixed.
Please re-open or comment to this issue when this issue remains.

peroon commented

同じ問題が私にも今起こりました。ojは最新です。

提出用formタグを見てみるとcsrf_tokenが設定されているようで、
一方ojのcodeforces.pyにはその記述はありません。

これは関係ないでしょうか？

I cannot reproduce this error now. All of consecutive eight submissions succeeded. It seems to be fixed, at least on my environment.

@peroon 分かりにくいんですが csrf_token は実はすでに含まれているはずです。<form> タグが解析され自動で送信されています。(リンク)
@peroon @Tard1grad3 Can you give me the detailed log ($ oj --verbose s https://... ... or something) with contexts (e.g. the first and second submission succeeded but the third submission failed.)? For this, please be careful not to include secret values like CSRF tokens. Thank you!

@kmyk This is my detailed log.
I've submitted 2-3 times, but all submissions have failed.
(I hid CSRF token.)

@hotaroon @peroon @Tard1grad3
I believe that I've fixed this bug by #125. online-judge-api-client package is updated to v6.1.0 now. Could you upgrade the package and check it again?

Thank you for checking!
It seems this issue remains even with the patch at v10.6.1. I'll try to fix this once again.

kmyk commented

I've investigated this issue further, and finally decided to keep it broken.
Please read #127. Sorry for inconvenience, and thank you for understanding.

Also, thank you @hotaroon @peroon @Tard1grad3 for helping me with debugging.
