Is there a firewall on a GROOV-AR1-BASE that might be preventing a remote connection to a tcp node running on its Node-RED server?
I created a test flow on the groov with just a tcp input node set to “Listen” on port 8000 (server). On my laptop I’ve tried connected to it on that port (using a couple of terminal programs) but it fails. I’ve also tried other ports like 4000 and 11000.
Alternatively, I have tried setting the tcp input node to “Connect” to my laptop (client) and that succeeds.
I’ve got a copy of Node-RED on my laptop and it doesn’t have this issue.
Will Node-RED on the groov not accept incoming tcp connections?
