Trezor Bridge Not Working? Here’s How to Fix It Quickly


Trezor Bridge is the essential communication link between your Trezor hardware wallet and your computer. If it stops working, your device might not be recognized, transactions could fail, or Trezor Suite may show connection errors.

If you're facing issues, don’t worry—most Trezor Bridge problems can be resolved with a few practical steps. This guide covers the most effective ways to troubleshoot and get your wallet working smoothly again.

What Is Trezor Bridge?

Trezor Bridge is background software that allows web apps and desktop programs (like Trezor Suite) to securely communicate with your Trezor device. If it fails, your browser or software won’t be able to detect your wallet—even if your device is plugged in.

Signs Trezor Bridge Is Failing

You might notice the following symptoms:

  • Trezor Suite can’t detect your device
  • Browser prompts say “Connect your Trezor” even when it’s already plugged in
  • You’re stuck on a loading screen in the wallet interface
  • Firmware updates won’t start or finish
  • Unexpected errors appear when trying to send coins

These are often signs of a communication failure between your computer and the wallet caused by Bridge-related issues.

Step-by-Step Fixes

1. Restart Everything

Before jumping into advanced fixes, reboot your computer and unplug your Trezor. Sometimes a fresh start clears up background conflicts or USB port issues.

2. Reinstall Trezor Bridge

An outdated or broken installation is one of the most common causes of Bridge failure.

To reinstall:

  • Uninstall the current version of Trezor Bridge from your computer.
  • Go to the official Trezor website and download the latest version of Trezor Bridge.
  • Install the file and restart your computer afterward.

3. Check Your USB Connection

Faulty cables or ports can interrupt communication.

  • Try using a different USB port.
  • Use the original Trezor cable or a high-quality replacement.
  • Avoid using USB hubs or extension cables—connect directly to your PC.

Browser Troubleshooting

Trezor Bridge works with compatible browsers like Chrome and Firefox. Problems may arise from outdated versions or conflicting add-ons.

4. Update Your Browser

Make sure your browser is running the most recent version. Browser updates often fix bugs and compatibility issues.

5. Disable Browser Extensions

Some browser extensions—especially security or privacy ones—can block communication with Trezor Bridge.

  • Temporarily turn off all extensions.
  • Refresh the page and check if your Trezor is detected.
  • If successful, re-enable extensions one by one to find the one causing the problem.

6. Clear Cache and Cookies

Corrupted cached data might be interfering with Bridge access.

  • Clear your browser’s cache and cookies.
  • Restart the browser and try again.

System-Level Checks

7. Check for Conflicting Software

Firewalls, antivirus software, and VPNs can block connections between your Trezor and Bridge.

  • Temporarily disable your firewall or antivirus.
  • If this solves the issue, add Bridge and Trezor Suite to your software's allow list.
  • For VPNs, try disconnecting while using Trezor Suite.

8. Use the Right User Permissions

On some systems, especially macOS and Linux, you may need to grant permissions to run Trezor Bridge or access USB devices.

  • On macOS: Check System Preferences → Security & Privacy for any blocked apps.
  • On Linux: Ensure udev rules are properly installed. Trezor provides specific instructions for Linux users.

9. Test on a Different Browser or Computer

To isolate the problem, try accessing your wallet from:

  • A different browser
  • Another computer
  • A private or incognito browser window

If it works elsewhere, the issue is likely local to your original setup.

10. Check for Software Conflicts

Avoid running multiple crypto tools, wallets, or Bridge-related software at the same time. They might compete for USB access and prevent your Trezor from connecting.

Best Practices to Avoid Future Problems

  • Always install updates for Trezor Bridge, your browser, and Trezor Suite
  • Use high-quality cables and direct USB connections
  • Download only from the official Trezor website
  • Regularly check your antivirus and firewall settings for new blocks or restrictions
  • Avoid browser extensions that interfere with device connections

Conclusion

Trezor Bridge is a simple but vital piece of your wallet’s security infrastructure. When it stops working, it can feel like everything is down—but the good news is that most issues are easy to fix.
