Logged out of RS250; cannot login (user unknown) - Any known issues?

Hi,

About 9 hours ago, I started experiencing issues with my Rose RS250. It seems I got logged out for whatever reason and cannot login again. The dialog keeps telling me ‘Lid niet bekend’ (member not known / user not known).

Are there any central issues going on? Will it come back by itself or do I have to take action?

KR,
Jasper
