But no dice. There’s also inconsitencies between the pictures and the instructions, which leads me to think that this documentation is out of date.
I try to connect using the url structure given in the instructions, and I also try to connect using the webdav url given to me by the settings in Nextcloud web gui but still no dice. For reference, this is my webdav url according to my web gui: https://cloud.jackalope.tech/remote.php/webdav/
Which OS are you using? Windows native is known to be a bit buggy and I have seen it working one day and breaking the other with no obvious reason. On windows, I’d recommend some 3rd party software to mount webdav as a drive (there was even a free open source, was duck…something).
Linux should work; mac should work but performs not very good (it does a lot of mac-specific stuff which is not supported and creates a lot of noise in the logs).
