I run a new instance(server) on port=8000.
2.I run another instance(client) on port=5000.
[running]
I access localhost:5000 and i see UI that I can interact and run commands.
I access localhost:8000 and nothing displayed however command line displays output and executed commands by the client at localhost:5000 (assumption).
[later]
I run yet another (duplicate) instance of port=8000. This port rejects clients or rather the first instance says; "No, I was here first". I still can't use the desired app features.
I run another instance on port=9000 and access localhost:9000. I can use the app without worry.
[conclusions]
If port=8000 goes down then the entire system crashes. All data lost 😢
[exceptions handled]
