Networking question - Why can't I telnet to the load balancer port of the public ip from within the same server

I currently have an LB configured in rancher and has a pubic ip and port of and I can hit this without issue with my browser from outside the VM where rancher and the LB is running.

BUT when I try directly from the local VM using a simple telnet to the ip and port locally on the same VM where the LB is running, I get connection refused. I can only telnet using the ip/port as assigned by rancher staring with 10.42. why is that?

Version info:

      User Interface
      Rancher Compose

Sounds like you are hitting this issue.

indeed it is. thanks.
