Technical Tip: GUI faceplate of FortiGate fails to display while editing Interface Settings

[ssanga]

Description	This article describes an issue where the faceplate fails to load or keeps spinning when editing a physical interface or a one-arm sniffer interface.
Scope	FortiGate v7.6.4.
Solution	This article describes an issue where the faceplate (visual interface diagram) in the FortiGate GUI fails to load or remains in a perpetual spinning/loading state when editing a physical interface or a one-arm sniffer interface. This is a cosmetic GUI rendering bug that does not impact the underlying configuration or functionality of the interface but can hinder usability during configuration tasks. Navigate to Network -> Interfaces -> Select an interface -> Set status down -> Select undo. Navigate to Network -> Interfaces -> Edit one-arm-sniffer -> OK. However, refreshing the GUI page will allow the faceplate to load successfully. This issue has been resolved in: v7.6.5 (scheduled to be released in December 2025). v8.0.0 (scheduled to be released in March 2026). These timelines for firmware release are estimated and may be subject to change.
