Hardly understanding what you are doing.
What program are you using ?
What do you want to to do with vcn ?

I use vnc viewer to make a remote connection then in the remote connection i try to change network settings from the network icon.

You might not achieve that. You should use SSH and access the remote machine and modify the setting, with easy, I'd say.
The point is likely you try to modify the current working connection with different settings, so that's not possible.
