XG, SSLVPN Issues

Hello Community,

i have a little problem setting up SSLVPN for my XG. I´ve followed this article: https://community.sophos.com/kb/en-us/122769

When i try to setup a connection via sslvpn client, i receive the following error:

Tue Mar 26 15:13:54 2019 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Tue Mar 26 15:13:54 2019 TLS Error: TLS handshake failed

I´ve also seen in the log that the client tries to connect to 192.168.0.1 which is the internal ip address of my XG, so i changed the configfile to the public ip like this:

remote my.public.ip.adress 443

Now i see that ip address in the log but still same error message.

The XG is accessible from remote via VPN, telnet to port 443 is open.

Question: Why comes the config file from the userportal with a wrong (private) ip address?

Why can´t i access the network?

Thanks!!
