Website Error On Load

• Try to log in to the management UI from a different device.
• Try to view other websites from the same device.
• Try to open the management UI with a different browser.

Service Unavailable Error

When you try to open the management UI from a browser, you see this message:

Service Unavailable - Zero size object
The server is temporarily unable to service your request. Please try again later.

This error might occur when you log in to different WatchGuard Endpoint Security accounts and the login process corrupts an HTTP cookie. To resolve, clear the cookie cache of your browser and try again.
