I'll post to github if noone sees an obvious user error and there are no suggestions to try.
Joplin version: 2.8.8
OSes: Ubuntu 22.04, Fedora 36
Syncing to Nextcloud server on the web, running ubuntu 22.04.
I can connect to Nextcloud and successfully copy files to/from there using Dolphin file manager.
Sync settings:
Joplin Sync target: Nextcloud (have also tries WEBDAV after repeated failures)
WEBDAV URL: https ://mydomain.com/remote.php/dav/files/username/Joplin
username and password set and have been check and verified by me
No matter if Nextcloud or webdav syncing used, I always receive the following error:
