I have 4 PCs in my home that run minecraft. All are Windows 7 machines and all are running 1.7.4. All of them can join any game opened to LAN on any others with two exceptions: When PC #3 tries to join a LAN game on PC #4 or when PC#4 tries to join a LAN game on PC#3, they will both get the infamous "Internal Exception: io.netty.handler.timeout.ReadTimeoutException" error and cannot join the game.
So far, this ONLY happens when those two PCs try to join a LAN game that is hosted on the other PC. There are no issues playing on any server we've tried yet. Also, there is no issues when PC#3 and #4 join a LAN game on PC#1 or #2.
The problem only occurs between PC#3 and #4. Nothing we have tried seems to have helped. We have not tried uninstalling minecraft and reinstalling yet, but we will try that tomorrow and post back an update.
Other than an uninstall/reinstall, does anyone have an idea as to what might be causing this?
So if PC1 hosts a game, all 3 of the other computers can join at the same time without issues?
Because if PC3 & 4 had the same IP address I would expect them not have trouble talking to each other, or being used at the same time.
Yes, if PC1 hosts a game, all 3 of the others can join at the same time with no issues. We routinely play a LAN game from PC1 with no issues. If PC2 hosts a game, we also have no issues with the other 3 joining at the same time.
PC3 and 4 do not have the same IPs (3 ends with .11 and 4 ends with .20).
You got me thinking about what we haven't tried yet. Neither PC3 nor PC4 can open a game to LAN and have any other PC successfully connect to it. Like a big light bulb going off in my brain FIREWALL. Checking the firewall settings on PC3 and 4 found that Java was not checked to allow connections. I gave Java firewall permissions on both, and we were able to connect them through a LAN game.
Thanks for kickstarting my brain, gerbil.
