Couldn't connect to LAN server

I tried to play with my wife, but we couldn't connect to the server hosted on my PC. It used to work fine.
I checked firewall permissions - both dontstarve_dedicated_server_nullrenderer_x64.exe and dontstarve_steam_x64.exe are added to the list
Both executables are set to run as administrator (and the window asking for permission appeared)
One thing that looked suspicious - I looked into cluster.ini and there were next values

[SHARD]
bind_ip = 127.0.0.1
master_ip = 127.0.0.1
master_port = 10888
cluster_key = defaultPass

But c_connect(192.168.0.<my_pc_real_ip_in_lan>, 10888) lead to "server is not responding" error
Then I checked netstat -aon
 UDP    0.0.0.0:10999          *:*                                    7740
 UDP    127.0.0.1:10888        *:*                                    7740

It finally connected with c_connect(192.168.0.<my_pc_real_ip_in_lan>, 10999)
