Shared folder its showing "Storage is temporarily not available"

[weedfish]

Steps to reproduce

1. Migration from ownCloud 8.1.8 to Nextcloud 13.0.1 (oc 8.1.8 to oc 8.2 to nc 9 to nc 10 to nc 11 to nc 12 to nc 13.0.1)
2. Click a shared folder (not from the admin, only shared folders from the ldap users) its showing "Storage is temporarily not available"
3. Database shared folder has no differences with the old one from owncloud 8.1.8

Expected behaviour

Click a shared folder should open up

Actual behaviour

All shared folders are redirecting to the root by clicking them. Small popup is showing "Storage is temporarily not available". I haven't add an external storage to the system.

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.
