KDE Desktop Client can't connect anymore (timeout, no ask for credentials/password)

Desktop
1

I can not get a connection with my owncloud server anymore at the external address. When I change the address in the config file to the internal address in my private network the connection works fine. The client asks me for credentials and connects.
With the external address the client doesn't ask for credentials and times out. I have the same problem with the computer of a friend since deleting and recreating the profile. He is running Kubuntu 15.04.
I think, this problem is not server related, but KDE-Client.
For me, this problem exists since a while, I was using the internal address. But my friend cant.

Thanks for help, Stefan

Well, here is something wrong with your networking. The client above is simply not able to connect to the client https://www..../cloud. Either you have misspelled the name, or the service is not running on the machine, or dns, or an evil combination :stuck_out_tongue_winking_eye:

I think it's not a network problem. I didn't change anything, when the problem occurred.
I can access my owncloud with any browser under https://www..../cloud without any problems.

So I did some tests again.
What works:
- connection via browser to https://www..../cloud from internal network and internet
- mount https://www..../cloud/remote.php/webdav with davfs on command line (tested only from internal network)
- all android services (owncloud caldav, carddav, news, bookmarks, notes, ...) are working from internal network and internet
- owncloud client on https://internal-address
- dolphin connection on webdavs://internal-address/cloud/remote.php/webdav

What works not:
- owncloud client on external adderss https://www..../cloud
- dolphin connection on webdavs://www..../cloud/remote.php/webdav

Dolphin doesn't ask for credentials, even if I try to connect with non existing user via webdavs://nobody@www..../cloud/remote.php/webdav

So I think, it is a KDE related problem. Does somebody know, where I should post this?

Looks quite similar to what I experience since a few days. Client is 2.1.1. on Ubuntu 16.04 (laptop and netbook), desktop got an older version which runs fine.

I tried to look into the logs, but nothing is shown under the tree tabs in "activities". All other clients (web, Android app) work fine as ever.

Please use a recent version of the client (which is 2.2.3, see https://owncloud.org/changelog/desktop/)

Another spontanous idea: Can it be that the client wants to open your kwallet to get the credentials out, and the little dialog window is somewhere in the background?

You could check if your ownCloud credentials are stored in your kwallet and if that is properly opened.

I think it is an ipv6 related problem. When I am using the ipv4 address, everything works fine, but with the server name it doesn't. I think it is similar to https://github.com/owncloud/android/issues/616.
Thanks anyway, Stefan

Maybe relevant:

Interesting. ownCloud-provided clients aside, for a moment …

webdavs://136.243.60.151/remote.php/webdav
results in a trust routine for an SSL certificate-related error. A shot from that routine:

KDE SSL Information – Dolphin – *.owncloud-demo.com.png664x517 41 KB

I can opt to trust the certificate but still, Dolphin does not proceed to present an authentication dialogue.
