Fix Your Stream Deck’s ‘Device Not Supported’ Error With a Simple Login

Has your Elgato Stream Deck suddenly displayed a frustrating red “Device Not Supported” message where one of your custom buttons used to be? This widespread issue primarily affects users who rely on BarRaider’s widely-used plug-ins, which perform a verification check for StreamDeck.exe’s digital signature. The root cause stems from Elgato’s own digital certificate expiring unexpectedly, creating a conflict that the plug-ins interpret as an unsupported device. Fortunately, the solution is straightforward and doesn’t require technical expertise.

Simply close your Stream Deck application completely and then relaunch it. Before doing so, however, you must first log into the official Elgato marketplace directly through the Stream Deck software interface. This crucial login step allows the application to automatically fetch and apply the necessary updates to the affected plug-ins, resolving the certificate validation error. Once you have logged in and restarted the app, the red error badge should disappear, restoring full functionality to all your buttons and macros. This process ensures your device and its enhancements are properly synchronized with the latest valid security credentials from Elgato.
