I connect, even from the internet and I can see the file and folder structure. But! It is impossible to write, and sometimes even impossible to read.
How can I make all this finally work?
Moreover, your certificates for webdav are INACTIVE.

My system: F2-223, TOS ver. 6.0.650

Are you logged in as a superuser?

Yes, I'm connecting with administrator rights. This is my only user in the system who has all the rights.

Please verify whether the permission settings for the folder on the NAS are correct. Additionally, let us know the operating system of your computer.

If you are using a Windows system, please try connecting with a different tool.

A webdav folder has been added to the public folder settings. There in the folder settings it is "enabled" for "*" (if I understand correctly - "*" for any client? You don't specify what that value is anywhere). For the administrator account, of course read/write is allowed.

My system is Windows 11 pro. For some reason other webdav connects without any other utilities. It does not connect to TNAS. Connection via third-party utilities is possible (as I already said), but writing is impossible.

Hello, please provide the client you are using and its version number. We will forward this information to the product team for verification and get back to you as soon as possible.

Previously, we encountered compatibility issues with certain client versions, so we recommend trying a different version to see if the issue persists.

My client devices:
1. Windows 11 pro 24H2 build 26100.3476
2. MacOS Sequoia 15.3.1
3. Android 14, Samsung OneUI 6.1

I also used various software, such as Rui, Duck, and others who have the functionality to connect to webdav. The result is the same everywhere. I can see the file structure of the webdav folder, but I can't change/write/rename anything.

Please solve my problem.
I really need a working version of webdav.

By default, the WebDAV list for shared folders is empty, indicating full permission. This means that the “*” you added might be interpreted either way. Therefore, it is advisable to confirm whether your “*” signifies “deny” or “allow”.
If you continue to encounter issues, please contact technical support for assistance.

Yes, everything is specified correctly.

Translated from Russian, this is the “Edit Shared Folder” window.
Specifies
“client” = *
“permission” = allow
