Fixing Login Issues — Clearing Your DNS Cache

Sometimes your computer holds onto old internet data that can interfere with logging in. Clearing it out (called "flushing your DNS") is easier than it sounds! Just follow the steps below for your computer type.

Windows Users

First, figure out which version of Windows you have. Not sure? Click the Start button and search "About my PC" — it'll tell you right there.

Windows 11

1. Click the Start button and type PowerShell in the search bar
2. Right-click Windows PowerShell and select Run as Administrator
3. Type exactly: ipconfig /flushdns and press Enter
4. You should see a message confirming the cache was cleared
5. Head back to ESPN and try logging in again

Mozilla Firefox Users

• Firefox users can install the “DNS Flusher” add-on and follow instructions to clear the DNS cache.
• Return to ESPN.com and attempt to Log In

 Tips:

• When typing these commands, copy them exactly as written — spacing and capitalization matter!
• On Mac, it's normal for Terminal to show nothing after running the command — that means it worked!
• If you're still having trouble after following these steps, don't hesitate to reach out to ESPN Support.
