No folders / files found in WebDAV dir.

[MikolasFromm]

Hi,

I've been trying to spin up your Blazor-WebDAV-player project on Ubuntu 20.04. I got blazor working and then started to configure the WebDAV player itself.

I have WebDAV enabled on https://example.com/webdav, so I entered that to StorageUri field in appsettings.json. WebDAV is public, so username and password should not be required.

Still, the player's field for directories is empty when page reloaded, even the "Loading directories and files from WebDAV" text disappears. In the server log, there is nothing wrong except for one warn sign Failed to determine the https port for redirect.

I quess the problem is just in my lack of information and I would love to make it work.

Thanks

Ok, after some digging, I've found out how to set the URI and RootFolder correctly, so that the request is in the https://example.com/webdav form.

Now when "StorageUri": "https://example.com/" and "RootFolder": "/webdav/" is set correctly, I get another error in a console of the Ubuntu server:

Would you, please, give me a little hint, how to make it work @StefH? The only thing I know is that this error occurs when I hit the webdav - if the URI or RootFolder is wrong and not pointing to the real webdav, the error doesn't show up.

Many thanks,
