Sauce Labs is pleased to announce the release of Sauce Connect Proxy 4.6.4.

This release includes these changes. Use the download links to get that latest and previous versions.

Version NumberChange DescriptionRelease Date



  • Decluttering basic sc client log 
    • PROXY log level is now in sync with the sc client log level (originally PROXY always logged at debug level)
    • Less verbose default HTTP requests logging
  • Command line option --pac-auth now also works with -T 

Bug Fixes:

  • User should be able to readily identify and use dynamically assigned ports for expvar metrics service regardless of number of sc clients running on the same host (sc client does not exit when attempting to start HA pool without explicitly assigned expvar service port numbers)
  • Sauce Connect client will now successfully establish connection while using tunnel proxy with basic auth 

Internal tooling and improvements:

  • Startup sequence for HA mode is streamlined by removing checks for colliding tunnels
  • Improved connection stability by improving KGP connection diagnostics algorithm 
  • Expvar metrics endpoint configuration conforms to selenium port configuration
