I am having issues connecting to a local server I have. I am able to connect my client to other remote servers, as well I installed the Server on the client machine and I can connect with no issue. 

 

I am using the standard MC launcher

MC Forge - 14.23.2.2611

MC version 1.12.2

 

Steps I've taken / tried to get client to connect to LAN server 

MC server ip 192.168.1.102

Client ip 192.168.1.125

 

Server - Win 08 r2 / I have disabled both the local and Domain firewalls.There are no firewalls running on the machine. 

Ping - I can ping minecraft.net with no issue / I am able to ping throughout my local network as well

Flushed DNS cache on both client and server. 

Have DNS set to 8.8.8.8 set on both client and server

Tried Vanilla MC. I am experiencing the same symptoms

So the fix action was on the client side actually. There is a domain firewall. Even though you go to control panel to disable firewall for local and / private networks. The Domain one stays on. That needed to be turned off for it to work.
