Hello, I have been using ownCloud for about 9 months and I always get the same king of warning / error in the logs. I am not sure if this is something I should worry about as it looks like someone trying to access the server.
This as example:
{“reqId”:“Yxxxxxxxxxxxx-AUAAAAAM”,“level”:2,“time”:“2021-02-02T19:20:50+01:00”,“remoteAddr”:“xxx.xxx.30.53”,“user”:"–",“app”:“core”,“method”:“GET”,“url”:"/",“message”:“Trusted domain error. “xxx.xxx.30.53” tried to access using “hxxxxx.xxxxserver.net” as host.”}
I get many like this everyday from the beginning and with different IP addresses. ¿Is there anything else I should configure to avoid risks? I have set the HSTS and my domain is accessible with https.
Thanks in advance!

Server configuration
Operating system:
Ubuntu 18.04.5 LTS
Web server:
Apache
Database:
PHP version:
ownCloud version: (see ownCloud admin page)
10.6.0.5
Updated from an older ownCloud or fresh install:
Where did you install ownCloud from:
Signing status (ownCloud 9.0 and above):
Login as admin user into your ownCloud and access
http://example.com/index.php/settings/integrity/failed
paste the results into https://gist.github.com/ and puth the link here.
The content of config/config.php:
Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.
or
If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder
*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.
List of activated apps:
If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.
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 configuration (delete this part if not used)
With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud 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.
