KDE Connect can't send files
Error in journalctl:
Firewall rules are present to allow the ports.
Issue seems to be from KDEConnect using every single one of these ports for things that I don't recognise. I don't want to mess with it without knowing what I'm doing. Anyone know what I should do in this situation?

Solution
EDIT: The fix was technically restarting, but the error comes back again after a while.
