Are you trying to connect the client on the same machine as the server?
Your logfile is complaining about port 1194 being in use.
You can find the proces using that port with (as root):

Code: Select all

netstat -anp | grep 1194

[jonybdbd]

1) I have tried to connect the client on the same pc running server

then

2) i have tried from other windows PC to connect server but see the screen shot

[mwandelaar]

This message says the server is actively refusing the connection, meaning the port is closed and actively refused.
Which isn't so strange, as the server is running on port 1194 and the client is trying to connect to port 443. The client-config is mentioning port 1194.

Are you running an access-server client or something on your machine? Can you increase verbosity, using "verb 4", on the client and see if you can post the logging here?
