Basecamp Not Loading or Not Working

Workaround available Web (Chrome, Safari, Firefox, Edge) Updated October 21, 2026

Quick answer

Basecamp failing to load in a browser is usually a VPN, a browser extension or stale cookies. Check the status page, turn off the VPN, try a private window, then clear basecamp.com cookies and cache.

Most likely fix: Rule out an outage.

Symptoms

Pages hang, stay blank, images look broken or features stop responding in the browser, while Basecamp works for colleagues.

Why it happens

  • A Basecamp outage
  • VPN interfering with the connection
  • Browser extensions such as uBlock Origin, Grammarly or TamperMonkey
  • Corrupt cache or cookies
  • An unsupported or beta browser version

How to fix it

Try these in order — the most common fix is first.

  1. 1. Rule out an outage

    1. Check status.basecamp.com or the @37signals X account for an active incident
    2. If there is one, wait it out; 2026 incidents mostly lasted from under a minute to about 25 minutes

  2. 2. Turn off your VPN

    1. Disconnect the VPN
    2. Reload Basecamp

  3. 3. Test in a private window

    1. Open an Incognito/Private window (most extensions are off there)
    2. Log in to Basecamp
    3. If it works, disable extensions one at a time, starting with ad blockers, privacy tools, Grammarly and script managers

  4. 4. Clear cache and cookies (Chrome)

    1. Chrome > Delete browsing data
    2. Time range: All time
    3. Check Cached images and files and Cookies and other site data
    4. Click Delete data

  5. 5. Clear cache and cookies (Safari)

    1. Safari > Settings > Advanced > enable Show features for web developers
    2. Develop > Empty Caches
    3. Safari > Settings > Privacy > Manage Website Data, search basecamp.com and 37signals.com, Remove, Done

  6. 6. Update your browser

    1. Basecamp needs Chrome 120+, Edge 105+, Safari 17.2+ or Firefox 121+
    2. Avoid beta or pre-release browser builds
