Why Is McGraw Hill Not Working | McGraw Hill Connect Error

If the McGraw Hill app or website is not working for you, it is likely a local issue with your browser or a specific “hiccup” in their login server. Here is how to fix it immediately.


1. The Quick Fix (Most Likely Solution)

The vast majority of McGraw Hill errors (especially “infinite loading” or blank screens) are caused by browser cookies.

  • Clear Your Cache:

    • Chrome: Press Ctrl + Shift + Delete (Windows) or Cmd + Shift + Delete (Mac). Select “Cached images and files” and “Cookies,” then hit Clear data.

    • Safari: Go to Settings > Safari > Clear History and Website Data.

  • Try Incognito Mode:

    • Open a “Private” or “Incognito” window and try logging in. If it works there, the issue is definitely your browser cache.


2. Check for Specific Known Issues

  • SIMnet Users: There have been intermittent reports of slowness with SIMnet recently. If you are using this specific tool, it might be lagging, but it should still be accessible.

  • “Session Expired” Loop: If you keep getting logged out, your browser is blocking “Third-Party Cookies.” You must allow third-party cookies for McGraw Hill to work.

    • Fix in Chrome: Go to Settings > Privacy and security > Third-party cookies > Select “Allow third-party cookies.”

3. Are you launching from Canvas/Blackboard?

If you are clicking a link inside your school’s portal (Canvas, Blackboard, D2L) and getting an error:

  • The Link might be broken: Don’t use the school link.

  • The Workaround: Go directly to connect.mheducation.com and log in with your email and password there. This often bypasses the glitchy connection between your school and McGraw Hill.


4. Verify Official Status

If you have tried the above and it still fails, check if a new outage has just started:

  • Official Status Page: status.mcgrawhill.com

    • Look for “Higher Education – Connect” in the list. If it is green, the problem is on your end. If it is red/yellow, their servers are down.


Next Step:

If you see an error code (like “Error 502” or “A104”), please tell me what it is, and I can give you the specific fix for that code.
