I need help connecting Joplin with WebDAV

Hi everyone!

I am trying to configure Joplin to connect my QNAP nas to a folder where I want it to leave notes or Joplin database.
The problem I have is that I insert:

https ://192.168.x.x:port/Joplin

  • IP: ip of my local nas network. (Because I always access with vpn and I will always be on my local network).
  • port: https webdav port.
  • / Joplin: folder where I want to store Joplin information

The problem is that it tells me this error:

And actually in advanced settings I have custom TLS Certificates. Do I have to add what file there? I'm a bit lost and appreciate any help fixing this and syncing with my nas and Joplin.


You can try that but if it doesn't work you could also try enabling "Ignore TLS certificate errors"

Additionally, self-signed certs are not considered valid certs unless your CA cert is added to the local trust store. However, you got a different error.

e.g. if your NAS has a hostname like nas.local and an IP of, then your cert should have a CN=nas.local and 2 subject alternative names:

  • DNS:nas.local
  • IP Address:

Like I work although VPN network this is a solution for me.

I would like to know exactly how to install the SSL version but I still don't know how to generate certificates on my QNAP NAS to use here ...

Thanks :slight_smile:

I don't think I can give you a quick how-to TLS intro. This topic is truly complex (or can be), but you will find proper guides on the Internet. If you understand these guides, my comment will make sense and give you the correct way to fix your issue.
