While trying to connect to a WebDAV server (Nextcloud) I added a faulty address on accident. (See screenshot). This address obviously connects to nowhere, so clicking on it does nothing but bring up an error message. I then tried to remove this faulty connection from the Nautilus sidebar via right click > remove, but the "remove" option is greyed out.
How do I remove the faulty connection from the sidebar?
EDIT: This is the output from /etc/fstab:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

I also tried unmounting the server manually using gio mount -u since the "volume" in question is correctly listed with gio mount -l. This doesn't produce the desired result, though ("mount point not found").
