If your account status is reported in the account window as "Locked: -1", briefly shut down the application. This is done by clicking or right clicking on the SpiderOak One icon in your operating system's system tray, menu bar, or notification area, and selecting Quit. Once the application has fully shut down, relaunch it as you would any application. That is done via your operating system's start menu or screen, launchpad, or application launcher.
If you find you are still seeing the Locked -1 code, try Renaming the APPDATA folder for One and Reinstalling an Existing Device to clear any transient problems that could be causing the code to become visible.
We have also discovered a correlation between Locked -1 and out of date devices on your account. It does not matter if the devices are being used, just being present is problematic.
Please also note that Nord VPN has also been proven to be a connected to this occurrence.
As a bit of background, Locked -1 is a catch-all error code. It doesn't necessarily mean there is anything wrong with the account itself and in fact can (for the most part) be ignored. However if you are finding that you are having trouble with uploads or other parts of the application and you are also receiving that code then please contact customer support. When you do so, mention the lock code and the email address associated with your account.
