Cannot sign in or page is blank in the CircleCI web app

Overview

If you cannot sign in to or access the CircleCI web app at app.circleci.com, your browser may have retained outdated CircleCI page files after a web app update. Emptying the browser cache and doing a hard reload downloads the current files and can restore access.

This article applies to reports such as:

• “I can't sign in.”
• “We cannot access app.circleci.com.”
• “The CircleCI web app appears to be down.”
• “The page is blank” or “I only see a white screen.”
• “The page is stuck loading” or the loading spinner never finishes.
• “The app is not loading, but the CircleCI status page says everything is operational.”

Check the CircleCI status page first

Check status.circleci.com for an active incident.

• If an incident is listed, follow the updates on the status page.
• If the status page is operational, continue with the browser steps below.

Try a private browser window

1. Open an Incognito / Private / InPrivate window.
2. Go to app.circleci.com and try to sign in.

If it works in a private window, empty the cache in your normal browser using the steps below.

Empty the cache and hard reload

Chrome or Edge (Mac)

1. Open Developer Tools with Cmd + Option + I.
2. Right-click the reload button in the browser toolbar.
3. Select Empty Cache and Hard Reload.
4. Close Developer Tools and try app.circleci.com again.

Chrome or Edge (Windows)

1. Open Developer Tools with F12 or Ctrl + Shift + I.
2. Right-click the reload button in the browser toolbar.
3. Select Empty Cache and Hard Reload.
4. Close Developer Tools and try app.circleci.com again.

Safari (Mac)

1. Go to Safari → Settings → Advanced and enable Show features for web developers (or Show Develop menu in menu bar).
2. From the Develop menu, select Empty Caches.
3. Reload the page with Cmd + R.
4. Try app.circleci.com again.

Firefox (Mac or Windows)

1. Go to Settings → Privacy & Security → Cookies and Site Data → Manage Data….
2. Search for circleci.com and remove its site data.
3. Reload app.circleci.com, or use Cmd + Shift + R on Mac / Ctrl + Shift + R on Windows.

Still cannot access CircleCI?

1. Update and restart your browser.
2. Disable browser extensions, especially privacy, ad-blocking, or security extensions.
3. Try a different browser.
4. Try a different network, such as a mobile hotspot, to rule out VPN, firewall, proxy, or ISP interference.
