Google Drive not working after enabling HTTPS scan

TomWilsonFL
Yesterday I pushed the CA Root Cert to my clients using Group Policy, then later enabled HTTPS decrypt and scan for them. So far everything seems to be working well, except Google Drive for PC. It simply will not connect.

I added my test client to the "Transparent mode skiplist", and then it started working fine, so I know it is something in the Web Protection filter that is causing the issue. I have tried adding Exceptions for many Google Drive related URLs (listed here: https://support.google.com/drive/answer/2589954?hl=en) and adding DNS host groups for "drive.google.com" to the destination host skiplist, both with no luck.

Has anyone experienced this issue? Any thoughts?

Thanks,
Tom

    Was this working before you turned on HTTPS scanning?

    If so, try turning it off.  Start Google Drive.  Quit Google Drive.  Look at the logs for all web traffic coming from that computer.  Based off that information try creating your exceptions.

    Note:  When HTTPS scanning is off the log is only printed when the SSL connection is closed.  Therefore you have to close the app before you can see logs.

    You can also try configuring the IE/system proxy.

    And if that fails...  Wireshark on the computer running drive to see where it is actually connecting to.
