Sign-in problems

  • Use the same sign-in method each time (for example the same social account or email flow you used when you registered).
  • Open the site in a private or incognito window, or clear cookies for this site, then try again.
  • Check that you are on the real JJConnect website (correct address in the browser bar) before entering credentials.
  • If you use a work or school device, a firewall or browser extension may block login. Try another network or device.

JJConnect sign-in is handled securely by our authentication provider. If you see an error on their page, note the message (or take a screenshot) before contacting support.
