Can't create or write into the data directory stored on nfs share

Hello,
I read tons of forums/reddit/github about this problem, i spent weeks but no solutions yet.
I’m trying to install Nextcloud on small server and pointing /data folder on NFS (synology).
I create folder on synology, created www-data user and edited /etc/passwd and /etc/group to get id 33. Mounted NFS share and I tried with no squash and with root->admin too.

I tried to edit some configuration files:
- i # all lines “Check if there is a writable install folder.” and “Check if config folder is
writable.” inside the following files:
/usr/src/nextcloud/lib/private/legacy/OC_Util.php
/var/www/html/lib/private/legacy/OC_Util.php

My stack is:

From container I can surf and write files inside /data folder:

root@df1e02d24e66:/# ls -lha
drwxrwx— 4 www-data www-data 4.0K May 8 09:35 data

If i change 777 on synolgy side installation start but then i get warning about 777 permission.

Any help???

I am having the exact same issue with almost the exact same setup. Hoping for a reply.
