So on both attempts, I am getting a 401 Error which Nextcloud reports as an Internal server error and it directs me to the nextcloud server logs however there is nothing in the Nextcloud log to follow up with.

This is a new installation and I am a new Nextcloud user. Should webdav work out of the box or do I have to do any further configuration. I read the server user manual and did not see anything specific.

Settings->Administration->Overview

All checks passed.

I spent a large amount of time cleared all of the errors and verified the dav links are redirecting properly.

I do not know how to troubleshoot further since there are no Nextcloud error log entries generated from these access attempts.

I have also tried to access my webdav share using KDE Dolphin following the instructions in the Nextcloud manual.

I paste my URL, enter credentials, they are accepted, waiting for server reply…

Then nothing, a blank window with 0 folders and 0 files.

It tries several times but again the first reply is again a 401 error.

Again, nothing in the nextcloud log at all during this time.

Can anyone with Nextcloud experience help? The nextcloud error message says more details can be found in the log but there is nothing in the log. How can a user troubleshoot without any feedback. Shouldn’t these features work out of the box?

Is this a typical experience for Nextcloud?

I have more less same experience (NC version 22.2.0, Debian 11, Apache2):
With windows 10 and 11 I get HTTP/1.1" 401 error in logs.
With MAC OS Big Sur and Monterey - the same HTTP/1.1" 401
On MAC, if I use some third party app (CloudMounter, it is working fine, with ForkLift - does not work, same error)
From Ubuntu linux - working just fine.

Any idea ?
