Missing photos, webdav mount

I have run into issues with approximately 1% of my photos while scanning into Immich. Webdav mount in Docker host with read-only davfs from Nextcloud (so albums shared there are also included in Immich). Error messages in Docker logs, but unable to identify which photo (file path) it complains about. Is there something about my setup that creates this problem? Running v1.125.7.
