Possible Fix!
OK ... The problem we were having seems to be related to certain DNS Servers working with Lloyds. We usually use googles DNS Servers (8.8.8.8 AND 8.8.4.4). Using these I currently get an error. If I change the Primary and Secondary DNS to the OpenDNS Servers (208.67.222.222 and 208.67.220.220) I can get into the banking successfully. ... Hope this helps someone out there! :)
