If Tor Browser doesn’t connect, there may be a simple solution.Try each of the following:

  • Your computer’s system clock must be set correctly, or Tor will not be able to connect.
  • Make sure another Tor Browser or instance of 'Tor' is not already running on your system.If you’re not sure if Tor Browser is running, restart your computer.
  • Make sure that any antivirus program you have installed is not preventing Tor from running.You may need to consult the documentation for your antivirus software if you do not know how to do this.
  • Temporarily disable your firewall.
  • If Tor Browser was working before and is not working now your system may have been hibernating.A reboot of your system will solve the issue.
  • Delete Tor Browser and install it again.If updating, do not just overwrite your previous Tor Browser files; ensure they are fully deleted beforehand.

Issues with making Tor Browser as your default browser. If Tor Browser was working before and is not working now (especially after a re-install or an update), your system may have been hibernating. A reboot of your system, in that case, will solve the issue. Tor won't start on Windows when the folder path contains non-ascii characters. The Tor Browser does have its flaws, which we’ll go into a bit later. Suffice it to say that your Internet Service Provider (ISP) can detect when you’re using the Tor Browser, which can make you the target of increased surveillance by both the ISP and the government.


In most cases, taking a look at the Tor logs can be helpful in diagnosing the issue.If you’re having trouble connecting, an error message may appear and you can select the option to 'copy Tor log to clipboard'.Then paste the Tor log into a text file or other document.

If you don't see this option and you have Tor Browser open, you can navigate to the hamburger menu ('≡'), then click on 'Preferences', and finally on 'Tor' in the side bar.At the bottom of the page, next to the 'View the Tor logs' text, click the button 'View Logs...'.

Alternatively, on GNU/Linux, to view the logs right in the terminal, navigate to the Tor Browser directory and launch the Tor Browser from the command line by running:

./start-tor-browser.desktop --verbose

Or to save the logs to a file (default: tor-browser.log):

./start-tor-browser.desktop --log [file]
