Webdav problem with öäü

[pingu]

I use the webdav plugin with ILIAS. A few weeks ago ILIAS was updated and now folders with umlauts no longer work. It still works with "Map network drive" in Windows 10.
Does anyone have a hint?

It could be a problem with Unicode UTF-8. %c3%9c is the German "Ü" coded as UTF-8. Try the changing various Unicode options in the connection settings.

I tried the following setting, unfortunately it doesn't work either:
"Akzentzeichen in URLs als UTF-8 Unicode senden"

(checkbox now unchecked, in the first post checked)

I have searched for error 12168, and it seems to mean the following:
>>Error 12168 occurs when there is a request which cannot be directed automatically. It could be a redirect from http to https. Try checking the option "Secure connection (via SSL)" in the connection settings. ghisler(Author) wrote: "Moved Permantently" means that the entered URL is wrong.<<

Apparently the server tries to redirect you somewhere. Can you see anything in the log?
1. Enable detailed logging in the connection settings
2. Enable FTP logging in Total Commander, it also logs plugins: Confguration - Options - FTP.

>Try checking the option "Secure connection (via SSL)
I tried both, with and without Secure connection. I created two logfiles with the following configuration:
Image: http://www.jost.li/tc/Config.PNG

Connect => Doubleclick on folder Übungen => Disconnect (with error):
http://www.jost.li/tc/tcftp_Access_Übungen_Folder.log

Connect => Doubleclick on folder Uebungen => Disconnect (without error):
http://www.jost.li/tc/tcftp_Access_Uebungen_Folder.log

I can't see anything new.

According to the log, the server redirects you to the _same_ address each time you try to access the page with accents.
Could you retry the test with appended slash "/" in the URL? You can set this option in the connection properties (last option).

Unfortunately, it doesn't matter, the error is the same:

HTTP/1.1 302 Found
means that the Web server wants to redirect you somewhere else.

HTTP/1.1 302 Found
means that the Web server wants to redirect you somewhere else.

That "somewhere else" is an error page/document:

Location: error.php

It would perhaps be good to know what that error document is saying...

Is there a way to let the plug-in log the response (especially the body) for this redirect?

You need to contact me by e-mail for a private test version.
