Remote Access FAQ¶

Q: What is the correct WebDAV URL?: The full URL to use for WebDAV is: https://my.domain.tld/remote.php/webdav/, there have been reports that for native Windows WebDAV you might need: https://my.domain.tld/remote.php/dav/files/USERNAME with USERNAME being the username you would like to use.

Q: Can I access my Nextcloud instance using WebDAV?: Yes, please see Nextcloud WebDAV documentation for a complete overview. A simple mount for unix-like systems might look like this: mount -t davfs https://my.domain.tld/remote.php/webdav/ /mnt/target/path while making sure that the davfs2 package is installed. For Windows please additionally read these docs.

Q: Why does my Android smartphone’s browser not open: ``http://nextbox.local``: As of today the technology needed to use .local URLs is not supported by various (stock) Android browser(s). The mechanism is based on mDNS. One possible workaround is to use a 3rd party app like BonjourBrowser to discover all mDNS services in your network.

There are several other reasons why the access using http://nextbox.local may not work, further known scenarios are:

Using a Fritz!Box with the NextBox being connected via a LAN port and the client/browser is connected to the network via WiFI (WLAN), the Fritz!Box will block mDNS.

Q: I followed all guides and still cannot acquire the TLS certificate, what can I do?: The reason a TLS certificate cannot be acquired is nearly always the fact that your NextBox is not reachable from the internet. Make sure you have followed the Remote Access Walkthrough. If you followed the step-by-step instructions and it still does not work, very likely something is blocking the connection, typical candidates are router web administration features like: MyFritz!, Fritz Web Services or similar services, which are running on your router and thus blocking the traffic on port(s) 80 and/or 443. Switch them off and retry acquiring your TLS certificate.

Q: Why is my reachability with IPv4 not working?: If you have properly set up port forwarding and IPv4 connections (reachability test) are still not working there are good chances that your Internet-Service-Provider (ISP) does not provide a proper (public) IPv4 address to you. There are several (end-customer) internet technologies, which do not allow incoming traffic for the IPv4, which was assigned to you. An incomplete list is: private IPv4 address, DS-Lite connection or CarrierGrade-NAT (CG-NAT). All these essentially share one IPv4 address accross multiple users, thus block (incoming) traffic from the internet to you. Some ISPs allow upgrading to so-called full-stack connections, which should enable full bi-directional traffic for IPv4 and IPv6.

Q: Why do some devices fail to connect for my IPv6 configured NextBox?: Sadly, still not all ISPs and mobile-network providers (smartphones) do have full IPv6 support activated. This means, if your NextBox is configured for IPv6 only access, devices inside these networks will not be able to connect. The backwards-proxy does work as a workaround here, as it provides an IPv4 entrypoint to your NextBox independant of your other remote access configuration.
