Summary of the issue you are facing:
[Running Nextcloud on Asustor. Installed via Asustor App Central. During routine updates, system updated Nextcloud to the latest version which is 33.x but the old version was 31.x. Asus/Nextcloud should not allow this update to occur but it did and now I have no running version. I need to get a working version of 31.0.9 so that I can then try to upgrade to 32 and then to 33.
I can’t get to any logs as the docker container will not even start. I don’t know where to download the previous apkg files to try to manually install version 31 or version 32 and I don’t know how to manually run a docker command to try to do this.]
