After transferring my NC installation to another webhoster, now NC Calendar and Contacts work well with Thunderbird / Lightning and also with DAVx and CalDAV / CardDAV on my Android.
But I have a problem syncing files. The issue began with my mistake, when I had Nextcloud file syncing on my desktop computer running with the old server and KeePassXC accessing its database file, which is synced via NC.
I added the connection to my new NC instance on the new hosting, while KeePassXC was running. As a result, NC on the new server wanted to sync the KeePass database file, while it was opened and also connected with the old NC instance.
The sync did crash: Error downloading https://…nextcloud…keepass.kdbx - server replied: Service Unavailable.
What I already have tried, to get rid of this problem:
Of course I closed KeePassXC first and made a copy of the KeePass database file. Second, I deleted the connection of NC file-syncing to the old webserver, so that there is only connection to the new installation left.
Third, I opened the NC database on the server via SQL admin and looked for locked files, but there was no such record.
Fourth, I deleted the keepass database file from the local NC sync folder. But the error remained.
Fifth, I looked to the syncing files on the server via ftp. Because syncing did not work, the keepass database file still was there. After I deleted the file, the error did not go away.
Sixth: I searched on the server as well as on lokal folders, wether there were further copies of this keepass database file. I found several of them and deleted them all.
But the error keeps on and file syncing via NC is dead!
On the server, I found nextcloud.log in the folder data. After all the above steps it gives me the following two errors repeatedly:

How can I get rid of this problem? Perhaps the database file is registered in the NC SQL database on the server and NC looks at this file and when it does not find it, it will stop syncing service?
