NFS shares don't show any files

Nextcloud version (eg, 20.0.5): 24.05
Operating system and version (eg, Ubuntu 20.04): 22.04
Apache or nginx version (eg, Apache 2.4.25): 2.4.52
PHP version (eg, 7.4): 8.1.2

The issue you are facing:
Mounted nfs shares load slow or not at all. To clarify: smaller shares load slowly and larger ones don’t load at all (no folders/files).
Since there is no error message, I am struggling to identify the root cause.
Any help is appreciated!
