Windows 11 WebDAV error 59

Hello i have a problem with my nextcloud setup.

I’m running local server with Ubuntu Server 24.04, and docker on it. I created container with NextCloud, but when I’m trying to mount network drive on my Windows 11 machine it’s giving me error 59

Same resultas, when traing to use GUI of Windows

I assume you can log into your instance just fine via the Web UI via that IP address?

Are you really using HTTPS without a hostname?

It’s been a while since I setup my Windows clients with their WebDAV connections, but I believe their are some additional command line parameters needed (e.g. /user:xxx pwd):

I will way Windows is very sensitive about http versus https as well as the certificates involved from what I recall. Might be something there…
