Error message upon testing the connection

KOrganizer does not seem to communicate passwords containing certain non-ASCII characters correctly when communicating to a CalDAV server. In this case, a stable Nextcloud instance was used.

1. Add Calendar
2. Select "DAV groupware resource"
3. Fill in the username
4. Type in a password with certain non-ASCII characters, like 'ö', select "Next"
5. In "Use one of those servers" select "Nextcloud"
6. Fill in the correct host data
7. On the next dialog, click the "Test Connection" button

Upon testing the connection, the error with the following error message occurs: "An error occurred: There was a problem with the request. Invalid username/password (401)."

The login data should be accepted.

Linux kernel: 5.1.2
KOrganizer: 5.11.1
KDE Plasma Version: 5.15-1
KDE Frameworks Version: 5.58.0
Qt Version: 5.12.3 (built against 5.12.3)
Nextcloud: 15.0.7
All versions are the latest available versions.

Using a password only containing ASCII characters works as expected. The password has been copied, pasted, and checked for errors.

Sorry for the moment I can't test it as I don't have server support
Comment 2 Laurent Montel 2019-05-16 05:08:01 UTC
I don't have a caldav server for testing it...

I had the exact same error and struggled a lot to find the cause. Pure luck led me to this bug report. i'll add some words here so that future strugglers might find the solution via search engines.

So i tried to use Nextcloud 21 dav with KDE Kontact, but it got Error 401 while testing connection. 
Indeed, i had non-ASCII characters in password. 
Changing the password to standar only worked around the problem. not optimal, but finaly it works!

Thank you for confirming the issue, Daniel!
As other people can reproduce the issue, I'll be setting this bug report to confirmed now.

Laurent, David,

since the password is encoded in the caldav url, maybe we need some special coding magic with QUrl::setPassword?


I think I'm having a similar problem with a special character
