The issue you are facing:
On multiple computers, with multiple accounts on my instance, synchronization using the Nextcloud desktop client fails reproducible. When opening the client, discovery of remote changes starts as expected, but after a couple of seconds the synchronization fails with
An error occurred while opening a folder Error while reading: error:140E0197:SSL routines:SSL_shutdown:shutdown while in init
This happens each time the synchronisation starts, only very small syncs finish without an error. When running the nextcloud client from the command line, I get:
[OCC::AbstractNetworkJob::start OCC::LsColJob created for "https://<domain>/nextcloud" + "/path/to/folder" "OCC::DiscoverySingleDirectoryJob"

[OCC::FolderMan::slotFolderSyncFinished <========== Sync finished for folder [Nextcloud] of account [<user>@<domain>] with remote [https://<domain>/nextcloud/remote.php/dav/files/<user>/]
However, no error messages appear together with failing synchronisation. Only when starting the client, the messages below appear once. I have already updated and restarted both the client and the server machines, and also completely logged out and logged back in in the desktop client.
Any ideas how to further debug the issue? Is this a client issue, or a server issue?

The output of your Apache/nginx/system log in /var/log/____:
Lots of successfull PROPFIND messages until the error occurs in access_log:

No error messages in error_log.
This points towards a client issue. I will try downgrading as well
