Google Backup and Sync Tool
Relay users experiencing issues with Google’s Backup and Sync tool on their MacOS and Windows devices need to add the following domains to Relay’s Exclude from Decryption list:
The issue occurs because Google disconnects and prevents traffic from decrypting with Relay.
Note: Adding accounts.google.com to this list of excluded domains causes issues when Restrict Access to Google Apps Domains (Internet Access > Default Rules > General) rule is enabled in Relay. Our development team is working to resolve this issue.
