Troubleshooting Bank Connection Issues in Open Banking

Some banks, such as Chase UK, can only be connected via app-to-app authentication and will not connect through their website.

If you’re having trouble connecting to your bank, try the steps below. Open Banking connections can be affected by browser settings, app permissions, or temporary bank issues.

1. Check your bank login

Before reconnecting with Emma:

• Log in to your bank through their website (not the mobile app).
• Make sure your banking app is installed and working normally.

If you cannot log in directly with your bank, the issue is likely on their side.

Avoid making multiple connection attempts in a row, as this may temporarily block access. If it doesn’t work after two attempts, wait a short while before trying again.

2. Try a different browser

Some connections work better on certain browsers.

We recommend:

• Google Chrome
• Safari on Apple devices

Make sure your browser is updated to the latest version.

3. Check device permissions

On some devices, security settings can prevent your bank app from opening during authentication.

For Android:

• Go to Settings
• Select Apps
• Select your browser
• Ensure it is allowed to open supported links

If this setting is disabled, your bank app may not launch correctly.

4. Reinstall your banking app

If you're connecting on mobile:

• Delete the banking app
• Reinstall it from the official app store
• Log in and confirm it works before reconnecting in Emma
