Hello! I understand you're experiencing a "Bad Gateway" error when trying to log in to the American Eagle FCU app and website. Let's try to get this sorted out together.

To start, can you tell me if you've tried accessing the app and website on different browsers or devices? Sometimes, this helps isolate whether it's a local issue or something on the server side.

Meanwhile, here are a few steps you can try on your Windows 10 device using WebKit-based browsers:

1. Clear your browser cache and cookies: This often fixes login and loading issues caused by corrupted data.
2. Try accessing the site in a different browser, such as Microsoft Edge or Google Chrome, to see if the problem persists.
3. Restart your device and Wi-Fi router to refresh your connection.
4. Check for any updates to the app via your official app source and update it if needed.

The "502 Bad Gateway" error usually means that one server received an invalid response from another server, which often indicates a problem on the service provider’s side. If these steps don’t help, it’s possible American Eagle FCU might be experiencing temporary server issues.

If you can, please let me know:
- If the problem is only on the app or the website or both.
- Whether you are connected via Wi-Fi, VPN, or mobile data.
- If you see any additional error message or code.

From there, I can assist you with more tailored troubleshooting or guide you on contacting American Eagle FCU support if needed.

Are you okay to try these steps and share more details?
