Under one account, how to connect the second PC to the orchestrator

Hi everyone. I am using the uipath community. And I have been working well with the orchestrator in my own PC.
Recently I have gained access to a virtual machine in some kind of server.
So I tried to run uipath in this virual PC.
I am able to install the uipath studio community in this one. But I can only run uipath studio in offline mode. And I cannnot connect to Orchestrator.

What is the error that you are getting when you attempt to connect your robot?

If you try and go to Orchestrator in your web browser what is the treatment?

Could be outbound firewall rules if it is a connectivity issue, or if you are seeing a specific error would shed some light on what to look at next.

Thank you for your quick response.
I am a layman regarding computer so the terms I am using are indeed confusing.

Anyway I tried to connect my second personal computer to the orchestrator.
After watching some guide video on the youtub, I succeeded.
My second personal computer has successfully been connected to the orchestrator.
(A new machine has been added to my tenant)

Now the problem is when I start a job in my second PC locally via assitant, everything is ok.
But when I start the same job via the orchestrator, it will fail.

And I found out that the host identity is not the second machines but my first machines.

Is there a way to solve it?
