We have a Citrix secure gateway in comination with web interface 5.3 and it works fine. We host two sites. One is connected to a Xenapp 5.x environment with a secure ticket authority on a Xenapp 5.x server. The other site is connected to a Xenapp 6.5 server and that is working fine in combination with a xenapp 5.x secure ticket authority but when i connect to a Xenapp 6.5 secure ticket authority it is not working. In the eventvwr i see messages like "SSL handshake from client failed."and "Client IP sent bad ticket, connection dropped." and "Incoming Citrix Gateway Protocol downstream data could not be processed." What is wrong?
