Hi I have only started using node-red yesterday. I am not sure why but I cannot run the server without getting a "Connection Refused" error. I am still in very early stages so I believe it has something to do with the way I've installed it, even though it's pretty straight forward. This is the exception I am getting.

Have Pavlos,

that appears to be a bug with the node-red-contrib-ttn node - it has failed to connect to whatever it is configured to connect to and the node is not handling the resulting error properly.

You may want to raise this against the node here: https://github.com/TheThingsNetwork/nodered-app-lib

and in the meantime you may need to manually remove/delete the /Users/PavlosCh/.node-red/node_modules/node-red-contrib-ttn/ directory and then restart Node-RED. At least that way you will be able to continue... (albeit without the TTN being available)
