Troubleshooting Trezor Bridge Connection


If your Trezor device is not being recognized by your computer or browser, it could be due to a problem with Trezor Bridge—the background service that enables communication between your Trezor hardware wallet and your web browser. This guide walks you through common issues and how to fix them.

What Is Trezor Bridge?

Trezor Bridge is a small background application that:

  • Enables browser-based communication with your Trezor
  • Is required for using Trezor with web apps like MetaMask and Trezor Web Wallet
  • Runs automatically once installed

If the Bridge isn't working properly, your device may not be detected, especially in web-based environments.

Common Trezor Bridge Issues

Here are the most frequent problems users face:

  1. Device not recognized in browser
  2. Browser shows "Trezor Bridge not running"
  3. Bridge not launching after installation
  4. Conflicts with other wallet apps (like Ledger Live)
  5. Outdated or corrupted Bridge version

Step-by-Step Troubleshooting

1. Restart the Trezor Bridge Service

  • Close your browser completely.
  • Disconnect your Trezor.
  • Restart your computer.
  • Reopen your browser and plug your Trezor back in.

Sometimes a simple restart resets background services and clears temporary USB connection errors.

2. Reinstall Trezor Bridge

If restarting doesn't help:

  • Uninstall Trezor Bridge from your system:
  • On Windows: Use Control Panel → Programs → Uninstall a program.
  • On macOS: Delete the app from the Applications folder and empty the trash.
  • Reinstall the latest version by manually downloading it from the official Trezor website using a secure device.

Tip: Restart your system again after reinstalling.

3. Check Browser Settings

Trezor Bridge relies on your browser to function correctly.

  • Make sure cookies and JavaScript are enabled.
  • Try using a supported browser (Chrome, Firefox, Edge, or Brave).
  • Clear your browser’s cache and cookies.
  • Disable or remove browser extensions that could block USB or WebUSB communication (e.g., ad blockers, privacy tools).
  • Try using incognito/private mode to rule out extension conflicts.

4. Use the Desktop App Instead

If the Bridge continues to fail, consider using Trezor Suite Desktop, which doesn’t rely on the Bridge for communication. It provides a more stable experience and doesn’t require the browser to detect the device.

5. Check for USB Issues

  • Make sure your USB cable is working and supports data transfer.
  • Try another USB port or another cable.
  • Avoid using USB hubs or docking stations.
  • Use a direct USB connection for best results.

6. Update Firmware and Software

  • Make sure your Trezor device is running the latest firmware.
  • Update your operating system and browser to the latest version.
  • Revisit the official Trezor site to get the latest Trezor Suite and Bridge versions.

7. Disable Conflicting Software

Software such as Ledger Live, VPNs, or other wallet tools can sometimes interfere with Trezor Bridge.

  • Close or temporarily uninstall similar wallet apps.
  • Pause VPNs or firewall software that could block USB or local network communication.

When to Contact Support

If none of the above steps resolve your issue:

  • Take note of your operating system, browser version, and Bridge version.
  • Contact Trezor Support and provide a full description of the issue.
  • Avoid resetting your device unless you’ve already backed up your recovery seed.

Conclusion

Trezor Bridge connection issues are usually caused by software conflicts, outdated versions, or browser-related problems. A careful reset, reinstall, and system check often solves the problem. For web-based Trezor usage, keeping Bridge updated and your environment clean ensures smooth device recognition and operation.
