Q: My connection is failing repeatedly.
A: Modifying the Group Authentication fields in your client will cause your connection to fail repeatedly. This information comes coupled with the downloaded VPN client and, if you change it, you must re-import the profiles to correct the problem. To import the desired profile, right-click on allthruucsd or split, and select Save Link As.
