I love the Openhab ecosystem , but when i log in at myopenhab and i want to get forewarded to the NodeRed or Logviewer WebDashboard i get no connection. It seems so that, something with the routing is wrong.
As far as I am aware, you will not be able to access these through myopenhab.
They are separate application and not served by the OH port 8080.
You will need to configure a server with proper security to serve these ports. You will also need to open these ports on your router and set-up access rights.
Just to summarize what everyone else has said. Only stuff served up openHAB’s internal web server (i.e. OH REST API, contents of the conf/html folder) get proxied through myopenhab.org. myopenhab.org is not a generic proxy and does not allow access to any and all web services you may be hosting on your home network. You must figure out how to safely expose those to the internet safely so you can access them remotely.
