I was following the youtube video by technolife dad to installed a reverse proxy for Nextcloud on docker. One of the items in the video is apparently outdated - it says to add some extra arguments to the already-created nextcloud docker container. When I did this I got an error message. I clicked out of them intending to go to the logs. Then the container was gone from the container list. I think the root problem was that the nextcloud ended up being part of two networks - I could see this in the network tab. I removed one of them.
If I go to shellinabox I can restart the nextcloud container so I assume that it is still there. Is there a way to reset it somehow?
