What Causes Under Armour Checkout Not Working?
When attempting to complete a purchase on Under Armour’s website, you might encounter issues that prevent the checkout from working properly.
1. Browser Incompatibility
Occasionally, outdated or unsupported web browsers struggle to handle modern websites’ checkout processes. For instance, cluttered cache or corrupted cookies can interfere with website functionality, leading to problematic checkouts.
2. Network Issues
Connection problems on your end may disrupt communication with Under Armour’s servers.
3. Payment Gateway Errors in Under Armour
Sometimes the issue is with the payment gateway itself, which can be down or rejecting the transaction due to various reasons such as incorrect payment details or fraud prevention measures.
4. Ad Blockers And Extensions
Third-party browser extensions, especially ad blockers, have the potential to block necessary scripts that run the checkout process.
5. Server Issues In Under Armour
During periods of maintenance or when updates are being applied, checkout functionality may be temporarily unavailable.
How To Fix Under Armour Checkout Not Working?

To Fix the Under Armour checkout not working, check your internet connection and update your browser. Additionally, update your payment information to resolve this issue.
1. Check Internet Connection
Ensure that your internet connection is stable and strong. A poor connection often leads to difficulties with online transactions.
Check your Wi-Fi or cellular signal
Look for the Wi-Fi signal or Ethernet connection indicator on your device. This is usually found in the system tray on Windows, the menu bar on macOS, or the status bar on mobile devices. A full signal indicates a strong connection.
Check for Local Network Issues:
- If you’re on Wi-Fi, check if other devices on the same network can connect to the internet.
- If you’re using a wired connection, ensure the Ethernet cable is securely plugged into your computer and router.
Restart Your Router and Modem:
- Unplug your modem and router from power for at least 30 seconds.
- Plug the modem back in first, wait for it to fully boot up, then plug in the router and wait for it to boot up.
Run a Network Troubleshooter:
- On Windows, you can use the built-in network troubleshooter by going to Settings > Update & Security > Troubleshoot > Internet Connections.
- On macOS, use the Wireless Diagnostics tool found in the Utilities folder.
Check Your Speed:

Use an internet speed test website like Fast.com or Speedtest by Ookla to check your connection speed. This can help determine if your internet is slower than expected.
2. Try A Different Browser
Sometimes, a simple fix like switching your browser can work wonders.
