Description Vuk Mirovic 2021-01-06 12:38:41 UTC 
SUMMARY

I have installed kdeconnect on both pc and android phone, they are on the same network but can't find each other, pc is 192.168.1.4, phone is 192.168.1.2.

I tried troubleshooting. I can telnet from pc to android phone 192.168.1.2 1716 succeeds and stays on, but I can't telnet from phone to pc with 192.16.8.1.4 1716, thou ss -tulpn shows kde daemon listening on 1716 for both UDP and TCP. 
When I try to locally connect with telnet 127.0.0.1 1716 connection is established but immediately dropped.
Don't have any firewall running and when I start http server on port 1716 on pc I can telnet to it from phone, so connectivity should not be a problem.

STEPS TO REPRODUCE
1. Try telnet to PC running kdeconnect on ip 1716 

OBSERVED RESULT
Connection is established and immediately dropped

EXPECTED RESULT
Connection stays on
