You can disable the web updater in the config which is the default when deploying via docker. The only time i had a mismatch is when i migrated from a nativ debian installation to a docker one and fucked up some permissions. And that was during tinkering while migrating it. Its solid for me ever since.
Again, there is no official nextcloud auto updater, OP chose to use an auto updater which bricked OPs setup (a plugin was disabled).
So basically the 4k remaster is not a remaster. I am disappointed.
