Security Server don't support Horizon Authentication?

Hi Experts

i want to access horzion desktop from outside of company, working with horizon workspace.

i configured load balancer, to map security server to an external ip.

but when i try to launch view web client from horzion workspace. it said connection server don't support horzion authentication method.

i configured security server for web client access in horizon workspace.

also when try to install WEB access at security server, it notice some error, maybe this is the reason?

very appreciate for your reply.

thanks

Best Regards

Bai
