Unable to access or browse Google File Stream (G Suite)

ProxySG Software - SGOS


Users are not able to access Google Drive File Stream attached as network share on user's computer. Files are not listed in the directories, or the directories are not opening. Files are not opening, but some of them are. 


Google Drive File Stream installed on Windows or Mac computers


  1. This issue might be caused by inaccessible URLs which Drive File Stream needs in order to operate properly. In order for users on your network to access Google Drive and Google Docs editors, your proxy and firewall rules should connect to the hosts and ports listed in the G Suite deployment guide for proxy and firewall. Otherwise, users may be blocked or denied access from these services.

  2. Drive File Stream is not able to properly respond to the 407 authentication challenge. Consider bypassing authentication for the URLs listed below in the "Solution" section. 


Allow for the access to the following URLs. Possibly, there may also be a need to bypass authentication for the URLs specified below. 

For the following hosts, [N] means any single decimal digit and * means any string not containing a period.

  • www.google.com:443/HTTPS
  • accounts.google.com:443/HTTPS
  • googledrive.com:443/HTTPS
  • drive.google.com:443/HTTPS
  • *.drive.google.com:443/HTTPS
  • docs.google.com:443/HTTPS
  • *.docs.google.com:443/HTTPS
