VPN Connection Woes

I am providing support for a client who recently started having problems with a vpn connection using Mobile User VPN 6.1.1. As far as I know nothing has changed about his environment. Here is what happens. He right clicks on the tray icon and clicks on connect.  The connection is made and he is prompted for his user name and password. The username and password seems to be accepted as there are no errors, but then instead of going forward a box pops up which says:  Unable to connect to My Connections\XXX.XXX.XXX.XXX-XXX.XXX.XXX.XXX.  Please check logs for further details.

Here is what the logs say (I x'ed out the external ip addresses for security purposes):

Sounds like there is a misconfiguration at the server trying to use a different encryption version than the client... Maybe see if there is a client update to match any server updates that were made?

Found out that the client needed to be upgraded. It was not an encryption issue. Thanks anyway.
