Sorry, I forgot that we need something to initiate the connection. Can you leave that running and then start ekos. You can create a new profile and select the "Remote" setting in the "Mode" section. Leave everything else as the default and save it. Then click the start button (play symbol) under "2. Start & Stop Ekos". Then I'm hopeful that you'll see some output in the terminal where you are running the indiserver command.
