External, cifs - authentication ok but no content

hi
I run of Centos 7.4 with:
nextcloud-httpd-10.0.4-2.el7.noarch
nextcloud-10.0.4-2.el7.noarch
nextcloud-mysql-10.0.4-2.el7.noarch

Server version: Apache/2.4.6 (CentOS)
Server built: Oct 19 2017 20:39:16
Server’s Module Magic Number: 20120211:24
Server loaded: APR 1.4.8, APR-UTIL 1.5.2
Compiled using: APR 1.4.8, APR-UTIL 1.5.2
Architecture: 64-bit
PHP Version: 5.4.16

Problem: I can configure CIFS external storage. Nextcloud confirms with green circle all is ok, I can also see on samba’s end that authentication works ok, but … When I go to actual storage then Nextcloud sort of goes, tries to get to the storage but shows no content and a second or two later shows “All files” page.

Snippet of Apache’s log:

Unfortunately I cannot get some more debug/info. Owncloud does not seem to create file in “data” folder, even though I set ‘debug’ => true,
It might be due to

If I use ‘log_type’ => ‘file’,

Hi,

That looks like the access log, can you output your error log please?
