We have launched six educational sites from our organsiation, These were loading fine during testing. But today all of them at that same time now get message below. They work from any other internet access. But acccesing these six pages throuh a Citrix connection to the web, gives me this message.
(Note that all other website can be accessed via Citrix just fine - just these six can't? Whats the connection?)
