trezor bridge — secure troubleshooting & common issues. Troubleshoot connection failures, origin prompts, port access, and steps to diagnose device connectivity with Trezor Suite and third-party wallets.
diagnose the basics
1. Confirm Bridge or Suite is running
Check your OS process list or system tray to ensure the Bridge service or Trezor Suite app is active. If Bridge is not running, open the appropriate application or re-run the installer.
2. USB & device checks
Try a different USB port and cable. Use direct ports instead of USB hubs for initial troubleshooting. Check device screen for any prompts requiring physical confirmation.
3. Browser origin & permission prompts
Web wallets must prompt the origin for permission. Accept origin prompts on connection and ensure browser extensions are not blocking requests. Clear browser cache if old origin state persists.
4. Firewall & security software
Local security software may block loopback ports. Temporarily disable or whitelist Trezor Bridge / Trezor Suite and test. Re-enable protections after verification.
advanced steps
If the issue persists after the basics, try a full uninstall followed by a fresh install from official sources. Back up your recovery seed before any firmware or recovery operations. Consult the Trezor guides for platform-specific uninstall steps and verify checksums for any installers.
