Same vpn connection on phone and PC

I know almost nothing about network connections, ports. ips, etc. Troubleshooting this stuff is so…
It should not be a device problem because everything works on Wndows and Fedora.

Problem

My PC and Android smartphone dont see each other. PC is connected by LAN and phone by WIFI in one network. Specifically Spotify don`t show my phone as connected devices and KDEconnect dont work. My phone dont see PC and PC dont see phone.

What I tried

I tried everything from kdeconnect-wiki…

  1. Checked connect is working and ports are open:
    sudo ss -tunelp | grep -i kdeconnect
    Output:
 udp   UNCONN 0      0                  *:1716             *:*    users:(("kdeconnectd",pid=28034,fd=26)) uid:1000 ino:193918 sk:5074 cgroup:/user.slice/user-1000.slice/user@1000.service/app.slice/app-dbus\x2d:1.2\x2dorg.kde.kdeconnect.slice/dbus-:1.2-org.kde.kdeconnect@0.service v6only:0 <->
  1. Added rules for firewall:
sudo ufw allow 1714:1764/udp
sudo ufw allow 1714:1764/tcp
sudo ufw reload
  1. Tried manual connection by IP. I used phone IP from my “wifi settings”, hope its right. Kdeconnect still see nothing
  2. Tried turn off VPN

Additional WIFI problem

For debugging I tried to connect my PC by WIFI. And Its disconnects instantly. Just disconnects after about 3-5sec after connection. GUI says nothing, I use Noctalia Shell V5 and I know nothing about network connections as I wrote befor, even can`t figure out where I can get proper logs.
