[Sophos Notification] Sophos XG Firewall: Device booting into safe mode after upgrade to v17.5

Hi Everyone,

A small subset of XG Firewall customers upgrading to SFOS v17.5 are experiencing an issue where the firewall is in a hung state and booting into safe mode due to a dead Garner service. This issue is related to an error caused by the Upstream Proxy configuration. This issue is to be resolved in SFOS v17.5.4 MR-4

Affected customers will need to rollback to their previous firmware version to recover the XG Firewall. If affected customers wish to continue the upgrade to v17.5, they will first need to rollback to their previous firmware version, remove the listed port in the Upstream Proxy configuration, then upgrade to v17.5. for more details, please refer the below KBA
