Hi Axel,

I had a similar problem, and could work around it with removing the user xxx@ from the url. KIO asked for username and password, saved it (again) to kwallet and connects fine now.

If that is the same for you, the bug is rather that the url handler does not recognize the user part correctly.

Hello Ben,
I needed to remove the user/PW from kwallet and log-in again, to get the folder overview working. 
But that did not bring complete success. As soon as I click a subfolder it claims 'invalid protocol'
journalctl:
Mär 30 13:15:15 X1E dolphin[25447]: kf.kio.core: Invalid URL: QUrl("")
(this time on wayland)

Can you copy the url that dolphin is trying to access roughtly?
Does it work if you add or remove the trailing slash from the url ?

> (this time on wayland)

Hardly have any incidence here.

Screenshot of error message

Backslash or not does not make any difference. It seems that the click on a folder does not return the proper folder name
If I go to the location bar and complete webdavs://webdav.mc.gmx.net/GNUHealth/ it determines the folder while I type and is able to change into that folder.

Another interesting fact - when in one subfolder, click on a subfolder is working as expected

For me this workaround didn't work. I still get "The file or folder ... doesn't exist".

I also found a downstream duplicate - https://bugzilla.suse.com/show_bug.cgi?id=1181988

It looks remotely similar but predates Plasma 6. These kind of problems pop up all the time and generally get dismissed by annoying self-proclaimed experts.

See e.g.: https://forums.opensuse.org/t/how-to-clear-dolphin-password-after-failed-sftp-login/170625/40

This might get fixed with https://invent.kde.org/frameworks/kio/-/merge_requests/1620 in KF 6.2

I also can't connect to webdav servers since Plasma 6. I tried to produce a test case today with a public webdav server at https://www.dlp-test.com/webdav_pub/
I noticed the following:
When I enter the URL webdav://www.dlp-test.com/webdav/ in dolphin, the connection works. When I change the URL to webdavs://www.dlp-test.com/webdav/ it loads forever, but the connection is never established.
So it seems related to the secure connection.
Can't see any useful information in journalctl.

I am running openSUSE TW 20240613 with KDE Frameworks 6.3.0 (and Plasma 6.0.5) but the bug is still occurring. Same error message. Removing the user from the URI sadly still doesn't help.

I encounter the same issue since upgrading Fedora 39 to 40. Now running plasma-workspace-common-6.1.3-2.fc40.x86_64).
Connecting to my photoprism webdav share (located at <baseurl>/originals) with Dolphin returns the error "The file or folder [...] does not exist.", when manually navigating to /originals/DCIM, the folder is listed and can be browsed recursively. 

When connecting to my Hetzner storage box Webdav, I can list the root (/) and see subdirectories, however entering those subdirectories returns the same "does not exist" error.

Both shares work using Thunar file browser.

Hello,

I'm in the same case than you after update from F39 to F40 no more WebDav from my nextcloud... but from an other device it's working fine... 

does not exist error are haunting me... 


Thinking that we must continue wait as KF 6.2 suggered in comment #8

A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kio/-/merge_requests/1738

After applying the linked MR I was able to browse the root folder of my Photoprism instance again. Verified on openSUSE Tumbleweed.

[webdav] Handle redirections which add trailing slashes

KIO doesn't always send trailing slashes when referencing collections.
The RFC (quoted in the comment) requires that such clients handle
redirections, which KIO can't do correctly in this case.

Add explicit handling for such redirections in the http worker, such that
KIO and applications don't need to be aware of this.

Hello, I can confirm this issue on Linux Manjaro KDE (stable). WebDAV functionality in KDE Dolphin has not worked since the KDE Frameworks update to 6.5.0 (I am currently using version 6.6.0). In contrast, it still worked correctly with Frameworks version 6.4.0.

I am receiving this error message:
>> The file or folder webdavs://domain.tld/daten does not exist

Interestingly, I can list the contents via the console, for example:
>> kioclient ls webdavs://domain.tld/daten/

As a temporary workaround, I am using Krusader, which works without any issues.
