Connection Refused on Install in Linux

[MechaWitch]

Been awhile since I've admined (1.7 was my last) and trying to get back in.

 

I'm trying to install forge 1.12.2-14.23.5.2838 within Ubuntu 18.04. I'm running this on a Hyper-V VM, 8 procs, 16gb ram. On running the installer I get a connection refused error...

There was an error during server installation

I figured, ok, maybe my firewall VM is blocking something, so I ran the installer locally and moved the universal file and libraries directory to the server after. Confirmed permissions were right after the move, then tried to start the server, but just getting "a problem occurred" right away...

So at this point... I'm a bit lost and not really sure what to do. any amount of searching hasn't helped. connection refused errors are impossible to sift through. Let me know if you have any ideas. Thank you.

........ I found the answer........

 

I have a PiHole setup in my VM network... That was blocking the connections due to the ads.
