This worked for me. More info here: KDE - ArchWiki
Hello, I tried your solution, but kdeconnect still fails to connect to Android devices. Here is my ufw status:

While kde connect shows:
So any ideas? Thanks for your attention!
Did you try to stop the firewall ?
I know this is marked as solved, but sometimes I have to open the app on my phone, or just unlock it, then it connects.
Also, I use Portmaster, for Kdeconnect I had to specifically disable âForce Block Incoming Connectionsâ for that one, too.
Hi~
I did this:
# [08:32:25] ~ took 35s $ sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

# [08:32:48] ~ $ sudo ufw disable
Firewall stopped and disabled on system startup

# [08:33:01] ~ $ killall kdeconnectd && kdeconnect-cli --refresh
After that, I open kdeconnect, but still cannot detect android devices. While both android devices can connect to each other. So any wrong step in my operations? Thank you any way.
Are you sure that both devices (PC and Android) are on the same network?
And according to your netcat, your network is 192.168.50.x. Normally, the local network is 192.168.1.x. Do you have a router?
See this post on kde discuss
Yes, I have a router. My PC connects to the router by cable. Android devices connect to the router by WiFi. The IP address of all devices lies in 192.168.50.x. I read this post but it doesnât work for me. It is confusing. Thanks for your attention 
, Iâll keep searching solutions, and update when I find solution.
PS: I came from Manajro several months ago, and never met this problem before. It is realy weird.
