The most common reason why signing fails, is the âToken signingâ extension on your internet browser. It needs to be âEnabledâ or âOnâ as in the newest Chrome browser.
When using Chrome - Double-check if you have the extension called âToken signingâ available and enabled (âOnâ). You can find it from the upper right corner Chrome menu by clicking on âExtensionsâ.
When using Firefox - Double-check if you have the two required extensions called âToken signingâ and âFirefox PKCS11 loaderâ listed and in âEnabledâ status. You can find them from the upper right corner menu by clicking âAdd-onsâ, then âExtensionsâ.
After changing the status of the âToken signingâ extension, you'll need to restart your browser by closing all tabs/windows of the browser and removing the card reader.
