ITS has identified an issue with the security certificate for vpn.queensu.ca. ITS staff are working to correct the issue.
When using the Cisco AnyConnect Client users will see a red error box with "Untrusted VPN Server Blocked!".
As a temporary workaround you can select "Change Setting..-">unselect "Block connections to untrusted servers". When you connect again you will receive a white error box with "Security Warning: Untrusted VPN Server Certificate!" You can then select "Connect Anyways".
