  • Take a look at these in your errors: 'TorBrowser\Tor\PluggableTransports\obfs4proxy.exe' failed at launch. 'TorBrowser\Tor\PluggableTransports\snowflake-client.exe' failed at launch. Either something is wrong with your installation, in which case you should uninstall and reinstall Tor Browser or there is something in your OS that is keeping this from running.

Well, speaking the things shortly - you've not understood the things under the hood and tried to ram them into the workflow. Now - in details.

  1. A Snowflake is not a pluggable transport itself, it's a browser plugin allowing people who are not censored to share their connection. There's no specific "snowflake transport"
  2. Your OBFS4 pluggable transport binary is not working - the error logs are clearly stating that. Grab a source and compile it by hand in GoLang locally - it is as easy as it sounds.
  3. Using any spaces in directory names confuses Tor, so just make them DOS-like, I'm using it like c:\\Tor\\... it just works
  4. Set a LogLevel to debug - yes, it produces a lot of text, but it really helps to troubleshoot things

If you need any further help - just drop me a line!
