Troubleshooting Tip: Certificate error when using SSL inspection after enabling Google Drive Sync
Description
This article describes how to resolve issues associated with Google Drive Application (Google Drive Sync), not the website, when the application does not work due a certificate error despite having an App Profile to allow it. This issue occurs due the drive.google.com site having SSL Decryption enabled, so the Google secure connection for Google Drive app will detect an invalid security certificate. If the FortiGate does not have a valid certificate, the application will not work.
This solution is oriented to an user computer that uses Google Drive Application (Google Drive Sync), so can be applied to any computer in the network.

Solution
There are multiple options for resolving this issue:
- Edit the shortcut for the Google Drive Sync and add the next 'switch' at the end:
-- unsafe_network
For example:
Original shortcut:
C:\Program Files\Google\Drive\GoogleDriveFS.exe
Shortcut modified:
C:\Program Files\Google\Drive\GoogleDriveFS.exe --unsafe_network2
- Open a Windows command prompt and navigate to the folder where Google Drive Sync is installed. During the prompt, run the following command:
googledrivesync.exe --unsafe_network
- Push out a registry entry change if Google Drive Sync is auto starting:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\GoogleDriveSync]
Add the value -unsafe_network after the quote:
C:\Program Files (x86)\Google\Drive\GoogleDriveFS.exe --unsafe_network /autostart
