TrueNAS and UrBackup

So I installed UrBackup on my Truenas the other day and forgot to create a user at first. I was having random issues of it not allowing me access to things. So I uninstalled the plugin from the Truenas GUI.
I chose to attempt starting fresh…or so I thought. For some reason now, when I install a fresh copy, it wont connect to the plugin at all. no matter how many times I try to uninstall/reinstall it refuses, even mapping the drive doesnt work.
Has anyone any ideas why it wont connect? I’ve a feeling its some remnant of the first install but cant find it.
Thanks in advance
