remote app Kept loosing connection to rds fram

Hi,

I manged to setup a 2008 R2 RDS Farm to publish remote apps onto web with the following setup

2xrdsh in MS- NLB

1xrd conn broker

1xrdweb/gateway

when i connect to RD Gateway: https://; i have set this up to forward to https:///rdweb and all is well i could login fine.

Web is configured such that it is looking at connection broker under web configuration settings

But when i click on any remote app i get the error as attached.

Any help would be greatly appreciated.

thanks
