KDE connect cannot find the phone how fix this problem?
Stop firewall first
systemctl stop firewalld
Then check if kdeconnevt finds your phone
Thank you now it works.
That's only the first step to check what was at fault - the next step will be to add the correct firewall rule so that you can have an active firewall as well as working KDE Connect functionality.
sudo firewall-cmd --zone=public --permanent --add-port=1714-1764/tcp sudo firewall-cmd --zone=public --permanent --add-port=1714-1764/udp sudo systemctl restart firewalld.service
