dear @shashank

As you know SecuExtender uses SSL on the HTTPS protocol..

Simpel test to see normally if you have setup things right is that you enter the adress you normally enter in SecuExtender in your browser.

Are you able to see the logon (webgui) of the zywall/usg

If not maybe you configured that intentionally, or else i think your port settings are not default.

That means if you change the https port you also should add the new port in the adress tab of secuextender like : 129.129.123.12:4433

Or are you behind a NAT router possible?

That means you have to port forward https to the zywall..

@Mark, Thanks for the hint.
@shashank
From the log, it looks like secure extender client is unable to connect to USG. please try it again with Mark’s suggestion.
