Windows Client Error

[Gary Hook]

I'm testing out Minarca in a home lab and running into a problem.  I have the server installed (per the docs) on a Ubuntu 24.04 server.  I'm able to log in to the server admin panel just fine.

When I install the Windows Client on a remote laptop (on the same subnet) and try to configure it I get the following error:

WinError 10061:  No connection could be made because the target machine actively refused it (see the attached snippet).

Obviously this is an SSH error but I can't figure out how to fix it?

Any help would be appreciated!

From the image you included, I read that it's referrring to
the URL failing, likely because the windows client is not
allowed to connect to port 443 on 172.20.2.202

You could test this from a windows cmd window with
curl -v https://172.20.2.202

On your ubunto server at 172.20.2.202 you could look and
see what is listening on port 443 (the https port) with
sudo lsof -i :443 | grep LISTEN

I suspect that you either have nothing listening, or you
have a firewall enabled on your ubuntu server that is
blocking the connections. I suspect the former.

Hope that helps

Yes, sorry i should have originally said that Minarca isn't listening on port 443.  I would have thought the standard installation of the server would open that port for Minarca but it didn't?  Any idea how to fix this?

Please disregard!  There seems to be an issue between Minarca and Ubuntu 24.04.4 LTS.   A fresh install of Debian Bookworm works perfect!
