Hi,
the server certificate of IDS Scheer timed out this week (30/03/2012). In order to make it running again you have to download the ssl patch and to install it on the server ****and**** on the client side.
Do not forget to put a reminder in your calendar, the patch certificate will expire in Spetember 2012.
Hope you have found this before investing hours in thinking about why 6?
Cheers,
Stefan
