How to setup terminal service gateway in my RDP client

Question

I am using "RD Tabs" to bypass the terminal service gateway to RDP to the remote host. Usually I use browser and go to https://webvpn.company.com:777 with my account.

Now in RD Tabs advanced settings, it's asking server name and authentication method. How should I fill this information?

I tried below:

server: webvpn.company.com:777
authentication: Attempt TLS

But it's not working, what could be wrong? Thanks.

If you use the Remote Desktop Client without RD Tabs, does authenticating with the TS Gateway using that same information work? I would focus on that first.
