Hi, I’m trying to deploy a nucleus server in a remote server (Linux), to which I have access via SSH (when I’m connected to a vpn). For this, I’m following this guide:
I put in the SERVER_IP_OR_HOST variable the IP of the remote server and custom passwords. I can pull the docker images with docker-compose with no problems and do docker-compose up. I can access the Nucleus Navigator at http://<SERVER_IP>:8080/omniverse://<SERVER_IP>/, but I got this:
Here are some logs of the containers:

I don’t know what I can be doing wrong, I tried to repeat the process (downloading new files from the NGC Catalog), but I end up with the same results.
My objective with this is to connect the a FlexSim simulator (installed locally) with a IsaacSim Simulator (5.1.0) (installed in the same remote server in a docker container) and have a live session between both simulators (In the different guides I have seen, a Nucleus Server is required for that).
Can anyone help me?
Thanks in advance!
