Cannot connect to sabnzbd

[jgw0]

sonarr version: 2.0.0.4753
Mono Version 4.2.3
AppData directory /home/greg/.config/NzbDrone
Startup directory /opt/NzbDrone
ubuntu 16.04.2

I cannot connect to sabnzbd. I have tested my sabnzbd downloader and it worked fine. I also tested the sabnzbd install and the server connection worked fine. I also ran sudo apt update and sudo apt upgrade, went to synaptic and had it fix any broken packages and upgrades (it found a couple more and upgraded them). I have no idea what more I can do.

Connection refused

This usually means that the wrong port was used or a firewall blocked it.

This morning I checked the logs to see what happened overnight. What happened was that sonarr did its thing and there were NO errors! There were a pile of them yesterday and, now, its magically stopped! (whoever says computers are simply logical machines are WRONG! (dealing with magic!)). Basing that on the simple fact that I have done absolutely nothing and was waiting for your response before having at it again. I have been at these things (computers) for a very long time and, I swear, asking questions can actually, and automatically, fix some problems!

Therefore, I thank you for your help. Even though it would seem that you didn’t you actually did! (the only reason I can see why the problems went away )

Have a good 4th!
