Problem with Rviz

Hi everyone! I'm trying to run Rviz with Ubuntu 18.04 (ROS melodic version 1.14.6). Firstly, I run roscore and then, in other window I'm trying to run Rviz but I can't. I set the command 'roswtf' for check the details, and It shows these:

Beginning tests of your ROS graph. These may take a while... analyzing graph... ... done analyzing graph running graph rules... ERROR: connection refused to [http://NOMADA7591:52180/] ERROR: connection refused to [http://NOMADA7591:52163/] ERROR: connection refused to [http://NOMADA7591:53496/] ERROR: connection refused to [http://NOMADA7591:52218/] ERROR: connection refused to [http://NOMADA7591:53385/] ... done running graph rules

Which commands are you executing?

roscore

and

rviz

??

Quite strange, seems like rviz goes resetting every instant.

In one window I have executed the command roscore, and in a new window I executed rviz

I have just solved the problem. I need that the server run in one window (first run 'export DISPLAY=:0' to set it, and then run the server with 'roscore). So we need to open a new window (the client), In one hand, in this window i set the Display ('export DISPLAY=:1'). In other hand, I run the graph enviroment (run Xlaunch and set window 1, for the Rviz (client)). So in the client window, i can run Rviz with the command 'rviz', and then the program will open.
