Hi,
I have similar error, when i use self hosted server. I have no problem when i use the default server.
I use the versions below:
6.10.10.0 host,
6.10.10.0 viewer,
2.8.2.0 server
When I try to connet to the host, the following message appears: "This authorization method is not enabled in remote Host settings", but the server show the active connection.
I use single password authorization, that you see in attached pictures.
I attached a diagram that show our networks.
Can someone help please?
