Trezor Bridge Not Working: Complete Solutions Guide

Common "Not Working" Scenarios

When Trezor Bridge is not working, users typically encounter these symptoms: device not detected, Bridge service not running, USB connection failures, or application timeouts. This guide addresses all major failure scenarios with proven solutions.

Symptom 1: "Bridge Not Found" Error

If you see "Trezor Bridge not found" message, the Bridge software either isn't installed or isn't running properly. Solution: Restart the Trezor Bridge service or reinstall from the official website.

Windows Fix: Open Services (services.msc), locate "Trezor Bridge", right-click and select Restart. If not listed, reinstall Bridge.

Mac Fix: Open Activity Monitor, search for "trezord", force quit if found, then relaunch from Applications folder.

Linux Fix: Run sudo systemctl restart trezord to restart the daemon. Check status with systemctl status trezord.

Symptom 2: Device Not Detected

Your Trezor device powers on but isn't recognized by Bridge. This usually indicates USB driver or cable issues requiring systematic troubleshooting.

Cable Testing: Try different USB cables. Many cables support charging only, not data transfer. Use the original Trezor cable or a verified data cable.

Port Testing: Test different USB ports on your computer. Avoid USB hubs which can cause communication issues. Connect directly to motherboard ports.

Driver Verification: On Windows, open Device Manager and look for "Trezor" under "Universal Serial Bus devices". If you see a yellow warning icon, drivers need updating.

Advanced Troubleshooting Steps

Complete Bridge Reinstallation

If basic restarts don't resolve the issue, perform a clean Trezor Bridge reinstallation:

Step 1: Uninstall - Remove existing Bridge installation through system settings or control panel.

Step 2: Clear Cache - Delete Bridge configuration files from your system. On Windows: %AppData%\Trezor. On Mac: ~/Library/Application Support/Trezor.

Step 3: Reinstall - Download the latest Bridge version from official Trezor website and install with administrator privileges.

Step 4: Verify - After installation, restart your computer and test the connection again.

Firewall and Antivirus Conflicts

Security software can block Trezor Bridge communication. Add Bridge to your firewall exceptions: trezord.exe on Windows, Trezor Bridge on Mac. Temporarily disable antivirus to test if it's causing interference.

Browser-Specific Issues

Some browsers or extensions interfere with Bridge detection. Try accessing Trezor Suite in a different browser. Disable privacy extensions like uBlock Origin or Privacy Badger temporarily to isolate the issue.

Linux-Specific Solutions

On Linux, Trezor Bridge not working often relates to permissions. Install udev rules: wget -O /etc/udev/rules.d/51-trezor.rules https://data.trezor.io/udev/51-trezor.rules then reload: sudo udevadm control --reload-rules && sudo udevadm trigger

When Nothing Works

If you've tried all solutions and Trezor Bridge is still not working:

• Test with a different computer to isolate hardware vs software issues
• Verify your Trezor device works in bootloader mode (indicates hardware is functional)
• Check Trezor status page for known service disruptions
• Contact Trezor support with detailed error logs and system information

For urgent issues, consider using Trezor Suite web version which doesn't require Bridge on some systems, or try the desktop application which has Bridge bundled.

Prevention Tips

To minimize future "not working" issues with Trezor Bridge: Keep software updated, use quality USB cables, avoid system interruptions during use, maintain clean USB ports, and periodically verify Bridge is running before connecting your Trezor device.
