I want to connect to Nextcloud, but it returns an error :
Error. Please check that URL, username, password, etc. are correct and that the sync target is accessible. The reported error was:
Try logging into Nextcloud, clicking on settings (1) in the bottom left hand corner of the "files" section, copying the WebDAV URL shown in the WebDAV field (2) and then adding /apps/notes if that is where you want to sync your notes to and you have already created the folders in Nextcloud.
