Setup details
Unraid version: 6.12.3.
I know this isn't the most up to date version, but after upgrading in the past, my server started having stability issues which took ages to resolve, and I don't want those headaches again. If I need to upgrade to address this issue I will, but I'm keen to avoid it if possible.

Background
I was following along with spaceinvaderone's tutorial (https://www.youtube.com/watch?v=U47nvwXrAOo) and everything was going well until I accidentally put the wrong subdomain into the 'New AIO instance'. I entered nextcloud.[domain] instead of cloud.[domain] and realised this was wrong as I clicked the Submit domain button (15:50 on the video).
I thought this would cause problems so wanted to go back and re-enter the correct domain, but there was no way to do this. There were no errors on the next page, so naively thought maybe it wouldn't be so bad, and clicked Download and start containers.
After a little while all the containers were downloaded and started successfully, but when I clicked Open your Nextcloud I got an 'unable to connect' browser error. I can't remember the exact error now, and if I reached out for help at that point I'm sure there would have been a simple fix, but I like to make things difficult for myself so ploughed on.
Thinking my initial fear of the wrong domain being entered during setup was the root cause I figured removing all the nextcloud dockers and starting again would be the best approach to take, seeing as it was very straight-forward the first time.
Current Problem
I have tried re-installing the docker multiple times after
deleting everything from the nextcloud share, deleting the share entirely, and recreating
deleting the nextcloud template from Docker > 'Add container'
using mc to delete the nextcloud-aio-mastercontainer directory from appdata
restarting unRaid
clearing my browser's cache (I was grasping at straws at this point)
Each time I re-install, the nextcloud-aio-domaincheck docker is NOT added, and I get the screen below when clicking on WebUI, even though none of these containers are actually present.
Request
What can I do to purge all memory of this container so I can start the whole thing from scratch and get the New AIO instance screen where I can specify the correct subdomain this time?
