Me and a friend have been having a hard time connecting to lan, with forge installed. We get the checksum failed, might need to reinstall error we are both using the same version of forge: 10.13.4.1614 we have also tried using the recommended version of forge: 10.13.4.1558 and no luck, we also got another error every once in a while which was: An established connection was aborted by the software in your host machine We turned of antivirus and firewall, as well as letting java threw firewall security on both machines.. Nothing works Minecraft Vanilla works perfectly. we both have the same mods, and they are all server compatible. John Charles
