I had this issue when running 18.0.1 (#19878) and fixed it by going to 18.0.2. The issue wasn't there in 18.0.3. Now, the issue has come back with 18.0.4.

The issue is present in four other systems running 18.0.4.

Steps to reproduce

Upload photo and/or video files to a folder.
Share folder.
Send link of shared folder to user.

Expected behaviour

Users can open folder and view files in the browser window.

Actual behaviour

Spinning icon and the file does not load or play in the browser.
Users have to download the files to view or play them.

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your Nextcloud installation folder

or 

Insert your config.php content here. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP config

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

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.

it's a known bug for nextcloud 18.0.4, that has been ennoying me as well...

see #20132 and https://github.com/nextcloud/files_videoplayer/pull/152#issuecomment-619622484

the only workaround right now is to do that :

as admin in "settings",

in "sharing" page and then "federated cloud sharing" section

check "Allow users on this server to send shares to other servers"

hope that helps you.

I spun up another instance of NC on the same basic platform. Here are what my tests have shown:

@Walterfilms , you are awesome! This fixed the issue for me.

I subscribed to those issues you posted to follow the progress.

@Walterfilms - This workaround solved my "video playback problem" after upgrade to 18.0.4 with public shares too! Thanks a lot!

Unfortunately this did not workaround the issue for me of being able to view images in a shared link visible in the browser - same 401 error as described in #20132 (Nextcloud 18.0.4), even after unsharing and resharing the directory after toggling the above settings.
