Isaac Sim installation - Omniverse server failure and gray scenario in isaac sim

Hi, I am writing because I am trying to install isaac sim on a machine with a MSI GeForce RTX 2070 GAMING Z 8G 8GB GDDR6 graphics card and Ubuntu Server 18.04.6 LTS (Bionic Beaver) as operating system.

During the installation in advanced mode (installation on server and use by remote connection) I have encountered multiple problems:

First of all, when I try to access Omniverse via web, I can login without problem, but once inside I can’t view the files and it repeatedly shows a server unavailable error message.

In addition to this error, when I run the file or, although I can access Isaac Sim, I notice that I can not perform the basic tutorials because I am not shown the scenario where to place the objects, instead the screen is displayed in dark gray.

I attach images of Omniverse via web, Isaac Sim with remote toolkit and the logs of both applications.

I hope you can help me. Thanks and best regards!
