How to Fix the "419" on Login


What is a 419 Error?


A 419 error means that your login session has expired or the security token used to verify your request is missing or invalid. This can happen if:

  • You’ve been on the login page for too long before submitting.
  • Your browser is blocking necessary cookies.
  • There’s an issue with cached data or browser extensions.


Steps to Fix the 419 Error


1. Refresh the Page and Try Again

  • Simply refresh the page (Ctrl + R on Windows, Cmd + R on Mac) and try logging in again.

2. Clear Your Browser’s Cookies and Cache


Sometimes, old cookies can cause login issues.


How to clear cookies and cache


Google Chrome:

  1. Click the three dots in the top-right corner.
  2. Go to Settings → Privacy and security → Clear browsing data.
  3. Select Cookies and other site data and Cached images and files, then click Clear data.
  4. Restart the browser and try logging in again.


Safari (Mac/iPhone):

  1. Go to Settings → Safari → Clear History and Website Data.
  2. Restart Safari and try again.


Firefox:

  1. Click the menu button ☰ and select Settings.
  2. Go to Privacy & Security → Cookies and Site Data → Click Clear Data.
  3. Restart Firefox and try logging in.


3. Try Incognito/Private Mode

Open your browser in Incognito mode and try logging in:

  • Chrome/Edge: Press Ctrl + Shift + N
  • Firefox/Safari: Press Ctrl + Shift + P
  • If login works in Incognito, clearing your cookies (Step 2) should fix it permanently.


4. Disable Browser Extensions

Some ad blockers, privacy tools, or security extensions may interfere with login.

  • Try disabling them temporarily and log in again.


5. Ensure Cookies Are Enabled

Make sure your browser allows cookies:

  • In Chrome, go to Settings → Privacy and Security → Cookies and other site data → Ensure Allow all cookies is enabled.


6. Switch Networks or Devices

If you're using a VPN, corporate network, or public Wi-Fi, try:

  • Turning off VPNs or proxies.
  • Using a different internet connection (e.g., mobile data instead of Wi-Fi).


7. Try a Different Browser

If the issue persists, try logging in using a different browser (Chrome, Edge, Firefox, Safari).
