Posted July 12, 20232 yr Hi, I am new to modding and this forum, please tell me if there is another post here that addresses my problem, I might have missed it. I am following the modding guide here, and I am at the bottom step (of the linked page) that is addressing starting and joining a localhost server. I run gradlew runServer and then separately gradlew runClient When I attempt to join the server by making a direct connection to localhost, minecraft gives me an invalid session error. What am I doing wrong here? Let me know if there is additional information I can provide to help. I have experience with Java, just not Minecraft Modding.
