Me and my friend were playing on our Minecraft server one day then the next day it wouldn't let me connect. The only difference in those 2 days was I changed my ethernet port in my router from ethernet 2 to ethernet 1. Now I get an io.netty exception connection timed out when trying to join. On hamachi I had the yellow triangle of death which comes and goes. Any help would be appreciated.
Edit: also cannot switch ethernet ports in the back of my router as this results in no internet.
