Nextcloud provides universal access to your files via the web, your computer or your mobile devices wherever you are. It also provides a platform to easily view and synchronize your contacts, calendars and bookmarks across all your devices and enables basic editing right on the web.

Key features:

  • configure Nextcloud with MariaDB and default access credential

  • integration with NethServer system users and groups

  • automatic backup data with nethserver-backup-data tool

  • customize HTTPS access URL (custom virtual host)


The installation can be done through the NethServer web interface. After the installation:

  • click on the Applications > Nextcloud item title or open the URL https://your_nethserver_ip/nextcloud

  • use admin/Nethesis,1234 as default credentials

  • change the default password

All users configured inside any user provider (see Users and groups) can automatically access the Nextcloud installation. After the installation a new application widget is added to the NethServer web interface dashboard.


Nextcloud update/upgrade procedure disables the apps to avoid incompatibility problems. Server logs keep track of which apps were disabled. After a successful update/upgrade procedure you can use the Applications page to update and re-enable the apps.

User list

All users are listed inside the administrator panel of Nextcloud using a unique identifier containing letters and numbers. This is because the system ensures that there are no duplicate internal user names as reported in section Internal Username of Official Nextcloud documentation.


If NethServer is bound to a remote Active Directory account provider a dedicated user account in AD is required by the module to be fully operational! See Join an existing Active Directory domain.


After installation, the application can be configured from the new Server Manager.

Custom virtual host

Sometimes it’s better to reserve a full virtual host for accessing Nextcloud like To configure the virtualhost, enable the Use a virtual host for Nextcloud option and fill the Virtual host name field.

Please note that after the configuration of a custom virtual host, Nextcloud will no longer be accessible from the default URL https://your_nethserver_ip/nextcloud.

If the machine is using Let’s Encrypt, remember to add the virtual host domain name to list of valid certificate domains.

Trusted domains

Trusted domains are a list of domains that users can log into. Default trusted domains are:

  • domain name

  • IP address

The list of trusted domains can be customized using Trusted domains field: add one domain per line.

CalDAV and CardDAV

Some CalDAV and CardDAV clients may have problems finding the proper sync URL and need automatic service discovery. Service discovery is enabled by default if a custom virtual host for Nextcloud has been configured.

To enable the service discovery even if Nextcloud is running on the default URL, check the Enable CalDAV and CardDAV auto-discovery field.


When enabling DAV auto-discovery, please make sure WebTop or SOGo are not already installed.

Collabora Online

See Collabora Online module from NethForge.


Since Nextcloud 18, ONLYOFFICE Community Document Server can be installed directly to the system without further configuration. To enable built-in ONLYOFFICE integration, access Nextcloud with the admin user then:

  • Go to Apps page and access Office & text section

  • Download and enable the ONLYOFFICE application

  • Download and enable the Community Document Server application. Please be patient, download and install will take a while.

  • Go to the Settings page and access the ONLYOFFICE application under Administration section

  • Verify the Document Editing Service address already contains the public address of your Nextcloud server


Installation of full ONLYOFFICE server is not supported on NethServer.
