NC 16 Update failed: Connection to LDAP server could not be established

 su - apache -s /bin/bash -c "source /opt/rh/rh-php72/enable; cd /usr/share/nextcloud/; php -dmemory_limit=512M occ app:list" | grep ldap
  - user_ldap: 1.6.0

I see user_ldap: 1.6.0

EDIT: I found this here in the community Connection between nextcloud and LDAP server could not be established

Same Problem?
