Can't Login to Codeforces on One Browser Profile (Cloudflare Verification Loop)

Hi everyone,

I'm facing a strange issue with Codeforces and wanted to know if anyone has encountered this before.

Problem

Whenever I click Enter on Codeforces using my main Chrome profile, I get stuck on the Cloudflare verification page:

"Performing security verification"

The loading animation keeps spinning forever and never redirects me to the login page. I can go through whole codeforces all fine even with the same gmail, I am only facing issues while logging in.

What makes this weird

  • The same Codeforces account works perfectly in:

  • Incognito mode

  • Another browser
  • Another Chrome profile
  • Other Gmail accounts can log in from the problematic Chrome profile.
  • The issue only occurs when trying to access Codeforces normally from that specific browser profile.

Things I've already tried

  • Cleared cookies and cache
  • Removed all Codeforces site data
  • Restarted the browser
  • Restarted the computer
  • Disabled extensions
  • Allowed cookies and JavaScript
  • Logged out and back in
  • Tried different networks

Unfortunately, none of these solved the issue.

Screenshot

I have attached it below.

Questions

  1. Has anyone experienced an infinite Cloudflare verification loop on Codeforces?
  2. Is there any way to reset whatever Cloudflare/browser fingerprint is causing this?
  3. Is there a fix other than creating a completely new browser profile?

Any help would be appreciated. Thanks!

MikeMirzayanov please help, sir!
