Hello, I am trying to host a modded server off of my old laptop and play the actual game on my PC. I port forwarded, got everything set up and ran the server on the laptop. The world and mods load fine and my friend can join (in another household/different IP). However, I cannot connect to the server off of my PC, which is on the same wifi/network as the laptop running the server. It just says "Can't connect to server" and every once in awhile the checkmark will appear, but I still can't join (see image).
Any reason as to why everybody (outside my household) can join except for other computers using the same wifi/network? Any responses are appreciated, it's probably something simple and I apologize as I am not well affiliated with all of these computer terms.
Notes (not sure if these matter):
-I have 2 computers on my network: the laptop connected wirelessly and my PC connected through an Ethernet cable
-I am hosting the server off of the laptop (can't connect using the IP address with my PC)
-using "localhost" works on the laptop to connect, not the PC
-The modpack is Age of Engineering (should not matter) and I have made sure I am using the same modpack version on my PC as the one the server is using
