Native Launcher Issues

I am trying to get the Native Launchers to work. I am using Windows, but keep running into errors when I manually input the gateway.

I get an “Unexpected end of file from server” error. I am trying to connect over the internet to our server and we only allow https connections. Am I missing something else?

For the manual URL if I were connecting at domain.org:9143 that is what I would put in the field right?

Thanks

You’ll need to put both the http and https ports into the URL if you are typing it in, like so: http://domain.org:8088:8043.
