KDE connect + firewalld not working, but correct ports are unblocked

After updating kdeconnect to 25.08.0-2, I'm running into a strange issue. I have 2 computers running kdeconnect with firewalld, they cannot see each other until I disable firewalld on both machines. No issues with connecting to my phone with firewalld active though.

The zone configuration is pretty standard, just the defaults with the kdeconnect service added:

home (active)
  target: default
  ingress-priority: 0
  egress-priority: 0
  icmp-block-inversion: no
  interfaces: wlp0s20f3
  sources: 
  services: dhcpv6-client kdeconnect mdns
  ports: 
  protocols: 
  forward: yes
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules: 

public (default, active)
  target: default
  ingress-priority: 0
  egress-priority: 0
  icmp-block-inversion: no
  interfaces: 
  sources: 
  services: dhcpv6-client
  ports: 
  protocols: 
  forward: yes
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

Verified that the correct zone is active on both machines. Clearly this is a firewall configuration issue - I'm hoping that someone knows what I have to unblock to make this work. Thanks

Re: KDE connect + firewalld not working, but correct ports are unblocked

There's a bug report on this issue over at KDE's bugtracker here. I'm not sure if this is a sound change from a network security perspective, but opening ports 40000-50000/udp for kdeconnect through firewall-config seems to have worked for me.

Re: KDE connect + firewalld not working, but correct ports are unblocked

Same issue here, even on a fresh install. Both my computers can see another one without a firewall, and can see my phones, but not each other
