I can't sign in

Find out why sign-in fails. Check your email address, password, account access, and browser, and fix the cookie error that says Request too large.

When sign-in fails, MangoMap shows a general credentials error instead of confirming whether the email is registered. Check these causes in order.

Check the email address

  • Check the spelling of the address and its domain.
  • Try another work address if you use more than one.
  • If your address includes a +tag, use the same address that was registered or invited.
  • If a team administrator invited you, use the address that received the invitation.

Check the password

  • Check Caps Lock and try entering the password again.
  • If you use a password manager, copy the password again rather than typing it manually.
  • If you do not remember the password, use How to reset a forgotten password.

Try the public sign-in page

If you are using an account-scoped page, try https://mangomap.com/sign-in. The public page works for any account and includes the password-reset flow. If the public page works, ask your administrator to confirm the account-scoped URL.

Check your account access

You can sign in only with an account membership associated with your email address. If you were recently removed from an account, or an invitation was never accepted, ask the account owner to check the Users page and resend the invitation if needed.

For a pending invitation, see Pending invitation troubleshooting.

Check your browser

Your browser must keep the session. Try these checks:

  • Use a normal browser window if you need the session to remain after you close the window.
  • Temporarily disable privacy or tracking extensions for mangomap.com and your connected custom domain.
  • Clear site data for MangoMap and try again. This signs you out of that browser, so use it after the other checks.

The page says “We couldn’t load this page”

The page reads We couldn't load this page and Your browser sent more cookie data than this site can accept. Clear this site's cookies, then sign in again. The browser tab shows Request too large.

Your browser holds more cookies for the site than MangoMap can accept. To fix it:

  1. In your browser settings, clear the cookies for the site in the address bar.
  2. Reload the page.
  3. Sign in again.

Clearing the cookies signs you out of that site in this browser.

If a reset email or code does not arrive

  • Check spam or junk.
  • Confirm the email address you submitted.
  • Wait a few minutes and request another reset.
  • Use the newest link or code if you requested several resets.

See How to reset a forgotten password for the complete flow.

Check service status

If the form is unavailable or sign-in fails for everyone on your team, check the MangoMap service status page before retrying.

If none of these checks work

Contact MangoMap support and include:

  • the email address you are trying to use
  • whether you are using the public or account-scoped sign-in page
  • whether you received an invitation
  • whether password reset sent an email or code
  • your browser and operating system

Do not send your password or a password-reset link.
