Initial setup SSH tunnel to Google Compute Engine Instance



I really held back from asking this question, but I have spent almost all day on this.
I have a Google Compute Engine Instance with Plex installed, but I can't connect to it via SSH tunnel for the initial setup.

VPC firewall rules
All ports for ingress and egress with source IP

From mac terminal
ssh -L 8888:localhost:32400

After visiting http://localhost:8888/web
channel 4: open failed: connect failed: Connection refused


PMS is not supported in that environment.


I ended up getting this working with the same command;

ssh -L 8888:localhost:32400

I don’t think PMS was running properly, so I reinstalled and checked it was running.
