System error - An error has occurred

This error message can arise from three different sources.

The error message usually occurs when a bookmark is used to directly access the log in screen.
If you use a bookmark the screen will display a message stating that you are logging in to an "Unknown service owner".

The error may occur if you use navigation buttons in the browser (back and forward) during log in.

If you have been automatically logged out due to inactivity you may also receive this error. If you update the web page you will gain access again.

If this does not help you must contact ID-porten User support.
